Dependency caching docs missing cache limits info

[vbuberen]

While checking out the documentation on dependency caching https://docs.codemagic.io/flutter-configuration/dependency-caching/ but couldn't find information on how long cache lives, its limits, etc. This is useful info for quite a lot of people as it seems to me.

Would be good to have something, like, for example, Github's docs with such info about their Cache action: https://docs.github.com/en/actions/using-workflows/caching-dependencies-to-speed-up-workflows#usage-limits-and-eviction-policy
