Invalidate cache on new version of texlive

[apriljunge]

Is there an existing issue for this?

Original problem

The cache-key is generated by profile-path and packages-path.
When these are not changed the texlive version is fixed.

On a long term this can break texlive (tlmgr) with the following error

tlmgr itself needs to be updated.
Please do this via either
  tlmgr update --self
or by getting the latest updater for Unix-ish systems:
  https://mirror.ctan.org/systems/texlive/tlnet/update-tlmgr-latest.sh
and/or Windows systems:
  https://mirror.ctan.org/systems/texlive/tlnet/update-tlmgr-latest.exe
Then continue with other updates as usual.
===============================================================================
tlmgr: Terminating; please see warning above!
tlmgr: package repository https://ctan.mirrors.hoobly.com/systems/texlive/tlnet (verified)

Proposed solution

The cache-key should consider the version or hash of the texlive installer.
As not updating will break the github action it's not needed to have this configurable.

Alternatives considered

One could generate the hash keys in the repos itself and pass it to this action or deactivate caching completely.
I think we should prevent people from deactivationg caches so I think this should be a package feature.
