I might be missing something, but can we simplify this by modifying the publisher rather than creating a new one and deleting the old one?

It wouldn't cover the case where the publisher is associated to more than one project: since the magic link is associated to a single project, it should only affect that project. And modifying a publisher would modify it for all associated projects.

Ah right, completely forgot about that case! It might be good to leave a comment to that effect (the current comment explains it indirectly, but an explicit one might stop an over-eager refactor 🙂)

What is this?
This PR adds two things:
This means changing a publisher that allows any environment so that it only accepts one.
The email suggests constraining the Trusted Publisher so that it only accepts the environment which was just used. The email also contains the magic link from (1), so that project owners can change the TP with only one click.
This fixes #17241
Details
Magic link
$MY_PROJECT$PUBLISHER_IDis a valid GitHub/GitLab publisher with no configured environment$MY_PROJECTEmail
** This is done in order to avoid confusion and edge cases: if a single Trusted Publisher is configured for multiple projects, to send an email during the token exchange we would need to send it to the owners of all the projects, which might be confusing if the token exchange was for the upload of a single project's release.
