PR label automation

[Kouteki]

Current state

Review team manually has to apply labels when they are reviewing PRs, which is wasteful labor, and sometimes does not represent the actual state.

Desired state

Labels are automatically applied by the github bot, and filtering by labels serves as the source of truth

Acceptance criteria

• When a new PR is opened by someone NOT on the Tech-staff team AND the PR is not in draft, apply the review/triage-pending label
• When a PR with review/triage-pending has been approved by anyone, remove review/triage-pending
• When a PR with is moved from open to draft, remove the review/triage-pending label (split to https://github.com/gnolang/gno/issues/3093 )

The current state of the bot should be able handle the two first points (related to labels). But I will need to implement the draft/ready for review detection.

Maybe we can first merge it, then add this feature afterward?

Yes please! Incremental progress is the way to go.
