chore: modernize issue/pull labeler action

This is based on the more-recently updated labeler.yml in the apm-agent-dotnet repo.

- Switch away from Alex's old unmaintained issue-labeler action.
- Remove old debugging "Show team membership" step.
- Stop assigning the issue to project 454 (and old GH proj we no longer use)
- The hope is that these changes will also close #3884.
