What article on docs.github.com is affected?

What part(s) of the article would you like to see updated?

The ref given is fully-formed, meaning that for branches the format is refs/heads/<branch_name>, for pull requests it is refs/pull/<pr_number>/merge, and for tags it is refs/tags/<tag_name>. For example, refs/heads/feature-branch-1.

Additional information

Surely github.ref is not refs/pull/<pr_number>/merge for an outstanding pull request.

My colleague tripped over reading this bit in canonical/operator#1451

Clarification:"
The difference is between on: pull_request and on: pull_request_target.

Hey @dimaqq! Thanks for finding this. We agree that the docs should be updated.

What do you think of updating the ref description reusable with something like this?

for pull requests events except pull_request_target, it is refs/pull/<pr_number>/merge.
pull_request_target events have the ref from the base branch.

This reusable is in the table here and in "Store information in variables"

Sounds good :)
