add tag expire workflow

[eumel8]

Motivation

as discussed this week, more and more tags are stored in the package repository. At this time there is no auto-mechanism to expire older tags, so I developed this action to maintain the package repo and delete older tags then 60 days.

Changes

• generate a PAT scoped package read/write
• added PAT to the repo
• added scheduled workflow

Tests done

manually tested on user/org package repo, works until the last tag is only present

TODO

• I've assigned myself to this PR

@Fovty I tested again and ended up with errors

Run ./venv/bin/python tagexpire.py *** user busybox%2Fbusybox 0 ^(latest|dev|[0-9][0-9]\.\d+\.\d+)$ 
/home/runner/work/_temp/f7ffa51b-7a5b-4f0b-8cc2-bb31343f77c5.sh: line 1: syntax error near unexpected token `('

I think this caused by the un-escaped characters in the runner shell. A working configuration is

"^dev$\\|^latest$\\|^2.0.0$"

but that's also not so reliable

Yeah, tested it right now in the shell - the error occurs, because the eval command is interpreting the special characters in the regex pattern as part of the shell command.

Had to do some escaping, but came finally to a working pattern (tested it locally).

Pattern: "^latest$\\|^dev$\\|^[0-9][0-9]\\\\.\\\\d+\\\\.\\\\d+$"

Alternatives for the RegEx:

• list of exclusions as argument
• file in repo with exclusions

suggestions are welcome

Closing, since we do not plan to implement this yet.
