open an issue automatically when a PR is merged on google/transit

[isabelle-dr]

In order to keep the validator up to date with the changes, we need to review PR's merged on the official specification to see if we need to modify a rule in the Canonical GTFS Schedule Validator.
Having an automatic issue would help to make sure we don't miss anything.

Additional context in:

• Keeping validator up-to-date with the spec #311

There is an interesting thread here: https://github.com/orgs/community/discussions/26323
One of the replies mentioned a GitHub app that we might be able to use, https://github.com/marketplace/webhook-actions

The logic would be: if REFERENCE.md is modified, we open an issue.
https://github.com/google/transit/blob/master/gtfs/spec/en/reference.md

Implemented! Waiting for next merge on reference.md to google/transit to test. It's on me to check this and mark this "done". Will likely take a few months for the next spec vote. cc @jcpitre @fredericsimard

@isabelle-dr No, it did. Here's an example: #1601

@fredericsimard @isabelle-dr Finally confirmed success from #1601, so closing now.

@fredericsimard Reopening for one more request with this: can we automatically add the "needs triage" label to any issue that comes from this workflow?

Certainly. See here: #1610
