[ci] fix test-frame-ui job

The test frame ui started failing consistently on latest master [1]. I
assume it was because of a race between
#1343 which introduced
this warning and a PR that updated our tooling version, hence the
warnings don't match perfectly, so regenerated them with
`TRYBUILD=overwrite` as the test suggests.
