Run spotless formatting (#958)

When we updated spotless's Java and Kotlin formatter, we changed the underlying
formatting rules.
However, due to spotless ratcheting, these formatting changes don't get applied unless a file
gets touched in a commit.

To avoid future PRs introducing lines of change that aren't related to the intention of the PR,
this is a one-time format of all files.
