This is necessary for an incremental migration to `rules_js` which
requires Bazel v6. Bazel v6 removed the managed directories feature,
which means we no longer can rely on symlinked node modules as the Bazel
repository; but rather need to duplicate dependencies. This is
okay/acceptable to enable the incremental migration.

We removed `bazel-toolchains` from the repository since dev-infra
provides the RBE platforms now (in a way where they are not reliant
on the Bazel version), so the comment in `.bazelversion` can be
removed.

Update to the latest version of bazel.
`4.0.0` introduced a breaking change on unnecessary backslashes and these
instance are corrected in this change.

This has a couple benefits:
- we now use a .bazelversion file rather than package.json to pin the version of bazel we want. This means even if you install bazel on your computer rather than via yarn, you'll still get a warning if your bazel version is wrong.
- you no longer end up downloading three copies of bazel due to bugs in both npm and yarn where they download all tarballs before checking the metadata to see which are usable on the local platform.
- bazelisk correctly handles the tools/bazel trick for wrapping functionality, which we want to use to instrument developer build latencies
