docs: regenerate platform version 2.0 from latest Next version (#68191)

## What

Regenerates platform documentation version 2.0 from the latest Next
(unreleased) version. This publishes all recent documentation updates
that have been made to the Next version as the stable 2.0 release.

Requested by Ian Alton (@ian-at-airbyte) via Slack thread:

## How

1. Deleted the existing `version-2.0` directory from
`platform_versioned_docs/`
2. Deleted the `version-2.0-sidebars.json` from
`platform_versioned_sidebars/`
3. Temporarily removed `"2.0"` from `platform_versions.json`
4. Ran `pnpm docusaurus docs:version:platform 2.0` to regenerate version
2.0 from the current Next version
5. Verified the build succeeds locally

## Review guide

1. **New content**:
`platform_versioned_docs/version-2.0/understanding-airbyte/cdc-best-practices.md`
- Comprehensive new CDC configuration best practices guide. Review for
technical accuracy.
2. **Sidebar changes**:
`platform_versioned_sidebars/version-2.0-sidebars.json` - CDC content
reorganized under "Sync Modes" section. Verify navigation makes sense.
3. **Terminology updates** throughout various files:
   - "Airbyte Open Source" → "Core" 
   - "Cloud Teams" → "Cloud Pro"
   - "Self-Managed Community" → "Core"
   - Verify these align with actual product naming conventions
4. **Content improvements** in access management, API documentation,
connector development, enterprise setup, and quickstart guides

## User Impact

Users viewing the version 2.0 platform documentation will see the latest
content updates, including:
- New comprehensive CDC best practices documentation
- Updated terminology reflecting current product names
- Improved clarity and accuracy throughout documentation
- Better organization of CDC-related content

No negative side effects expected - this is a documentation-only update.

## Can this PR be safely reverted and rolled back?

- [x] YES 💚

This is a documentation change only. Reverting would restore the
previous version 2.0 documentation content.

 If you want to use Python to move data, our Python library, [PyAirbyte](/platform/using-airbyte/pyairbyte/getting-started), might be the best fit for you. It's a good choice if you're using Jupyter Notebook or iterating on an early prototype for a large data project and don't need to run a server. PyAirbyte isn't an SDK for managing Airbyte. If that's what you're looking for, use the [API or Python SDK](#api-sdk).
 
+## Why Airbyte?
+
+Teams and organizations need efficient and timely data access to an ever-growing list of data sources. In-house data pipelines are brittle and costly to build and maintain. Airbyte's unique open source approach enables your data stack to adapt as your data needs evolve.
+
+- **Wide connector availability:** Airbyte's connector catalog comes "out-of-the-box" with over 600 pre-built connectors. These connectors can be used to start replicating data from a source to a destination in just a few minutes.
+- **Long-tail connector coverage:** You can easily extend Airbyte's capability to support your custom use cases through Airbyte's [No-Code Connector Builder](/platform/connector-development/connector-builder-ui/overview).
+- **Robust platform** provides horizontal scaling required for large-scale data movement operations, available as [Cloud-managed](https://airbyte.com/product/airbyte-cloud) or [Self-managed](https://airbyte.com/product/airbyte-enterprise).
+- **Accessible User Interfaces** through the UI, [**PyAirbyte**](/platform/using-airbyte/pyairbyte/getting-started) (Python library), [**API**](/platform/api-documentation), and [**Terraform Provider**](/platform/terraform-documentation) to integrate with your preferred tooling and approach to infrastructure management.
+
+Airbyte is suitable for a wide range of data integration use cases, including AI data infrastructure and EL(T) workloads. Airbyte is also [embeddable](https://airbyte.com/product/powered-by-airbyte) within your own app or platform to power your product.

 ## Contribute
 
 Airbyte is an open source product. This is vital to Airbyte's vision of data movement. The world has seemingly infinite data sources, and only through community collaboration can we address that long tail of data sources.
