build: update to bazel 6

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.
