bump(storage-8.3.0): from 8.2.1a0 to 8.3.0

[leanaha]

Summary

I only bump the storage version to 8.3.0 in pyproject.toml.

The correct way to do this should be to create an alpha version from my branch (not from master as I did). After testing it, merge my branch to master and create the minor tag/release.
In this particular case, I've already merged my branch to master and create the alpha version from master. Thus, the only thing left to do is to change the pyproject.toml version.

If you want to see what I added to master at that time, please see this link

In my opinion the creation of a new feature (i.e. list_buckets) warrants a minor version bump from 8.2.0 to 8.3.0.
