Disable cache

[soumeh01]

To clarify the rationale for disabling the package manager cache:

• The GitHub Action controls how often the cache is created, and we cannot configure the frequency.
• GitHub does not automatically clean up old caches, which can lead to excessive storage growth.
• Additionally, caching provides minimal performance benefit during builds.

Thanks, LGTM!
I agree with the he low benefit of caching, saw some experiments of yours yesterday and was 20 seconds or so. Let's turn it off until the downloads and installation become a real performance problem.
