build: build locale files for legacy saucelabs job (#42230)

Given that the locale files are now generated through
Bazel, the files are no longer checked-in and the
legacy TSC compilation fails due to imports resolving
to non-existent files. We fix this for the legacy
saucelabs job by copying the generated TS files into
the sources (which is acceptable for the isolated CI job)
