[QoL] Enabling auto-merge on Crowdin PRs

[shamoon]

Definitely just a minor quality-of-life thing, but I discovered GH 'auto-merge' which seems like it could be useful for our translation PRs. Essentially when we're ready we just review the PR and poof the rest happens (squash, merge). Apparently the REST API doesn't support it and we'd have to use GraphQL API (or gh cli apparently supports too) https://docs.github.com/en/graphql/reference/mutations#enablepullrequestautomerge

https://github.com/orgs/community/discussions/24719

Again, obviously NBD, for now someone can just open up the PR and click "Enable auto-merge squash" after it gets opened

I agree, that would be handy.

I wonder if something like

await gh.post("https://api.github.com/graphql", data=f"""
mutation MyMutation {
    enablePullRequestAutoMerge(input: {pullRequestId: "PR_ID", mergeMethod: MERGE}) {
        clientMutationId
         }
}
""".replace("PR_ID", pull_request_id))

would work with our existing API client.
