name: Create translation Batch Pull Request

# **What it does**:
#  - Creates one pull request per language after running a series of automated checks,
#    removing translations that are broken in any known way
# **Why we have it**:
#  - To deploy translations
# **Who does it impact**: It automates what would otherwise be manual work,
#   helping docs engineering focus on higher value work
