Updated pinned maven dependencies. (#6118)
Updated pinned maven dependencies. (#6118)

The versions of things in our workspace have been updated, but I noticed
that I wasn't getting access to some newer features (like `StateFlow`).
I discovered a note in `WORKSPACE` about artifacts being pinned. This PR
is the result of running the command to re-pin the deps.
