Fix bucket name being reused between instances of different buckets

[minhdanh]

:sparkles: What kind of change does this PR introduce? (Bug fix, feature, docs update...)

This fixes an issue in which a subsequent FirebaseCacheManager instance cannot load or upload files correctly because the bucket name was set and cached in the first FirebaseCacheManager instance. It also updates packages to latest versions.

:arrow_heading_down: What is the current behavior?

In my case when I try to read a file from another bucket I see error " [firebase_storage/object-not-found] No object exists at the desired reference." although the file is there.

:new: What is the new behavior (if this is a feature change)?

If we're initializing a FirebaseCacheManager with a new instance, it makes sure to use another cache key so that files from the other bucket can be read.

:boom: Does this PR introduce a breaking change?

No

:bug: Recommendations for testing

Hmm, not sure
