Deprecate non-expiring access tokens

Problem

In Ensure all non-expiring personal, project, or ... (#369123 - closed) we plan to remove support for any access tokens that don't have an expiry. These tokens will then get a populated expiration date of +1 year. This needs to be announced at least 3 releases ahead of time.

This post is to announce the deprecation of these tokens.

To identify/extend tokens

See #369122 (comment 1927926624) that was added to help reduce the impact of the token expiration
