Bump version to 10.0.0

The following PR's were cherry-picked:

* Excel & CSV query runner (#2478)
* Pin python3 image version (#5570)
* Fix: Edit Source button disappeared for users without CanEdit perms (#5568)
* Fix: Specify the protobuf version (#5608)

Plus one additional change exclusive to this branch:
* Replace reference to yarn with NPM

This happened because we cherry-picked #5570 but did not also incorporate
#5541 into V10.

 # Change Log
 
+## v10.0.0-beta - 2021-06-16
+
+Just over a year since our last release, the V10 beta is ready. Since we never made a non-beta release of V9, we expect many users will upgrade directly from V8 -> V10. This will bring a lot of exciting features. Please check out the V9 beta release notes below to learn more.
+
+This V10 beta incorporates fixes for the feedback we received on the V9 beta along with a few long-requested features (horizontal bar charts!) and other changes to improve UX and reliability.
+
+This release was made possible by contributions from 35+ people (the Github API didn't let us pull handles this time around): Alex Kovar, Alexander Rusanov, Arik Fraimovich, Ben Amor, Christopher Grant, Đặng Minh Dũng, Daniel Lang, deecay, Elad Ossadon, Gabriel Dutra, iwakiriK, Jannis Leidel, Jerry, Jesse Whitehouse, Jiajie Zhong, Jim Sparkman, Jonathan Hult, Josh Bohde, Justin Talbot, koooge, Lei Ni, Levko Kravets, Lingkai Kong, max-voronov, Mike Nason, Nolan Nichols, Omer Lachish, Patrick Yang, peterlee, Rafael Wendel, Sebastian Tramp, simonschneider-db, Tim Gates, Tobias Macey, Vipul Mathur, and Vladislav Denisov
+
+Our special thanks to [Sohail Ahmed](https://pk.linkedin.com/in/sohail-ahmed-755776184) for reporting a vulnerability in our "forgot password" page (#5425)
+
+### Upgrading
+
+(This section is duplicated from the previous release - since many users will upgrade directly from V8 -> V10)
+
+Typically, if you are running your own instance of Redash and wish to upgrade, you would simply modify the Docker tag in your `docker-compose.yml` file. Since RQ has replaced Celery in this version, there are a couple extra modifications that need to be done in your `docker-compose.yml`:
+
+1. Under `services/scheduler/environment`, omit `QUEUES` and `WORKERS_COUNT` (and omit `environment` altogether if it is empty).
+2. Under `services`, add a new service for general RQ jobs:
+
+```yaml
+worker:
+  <<: *redash-service
+  command: worker
+  environment:
+    QUEUES: "periodic emails default"
+    WORKERS_COUNT: 1
+```
+
+Following that, force a recreation of your containers with `docker-compose up --force-recreate --build` and you should be good to go.
