Update docker files to use Debian bookworm (#23543)

## Description

Update docker files to use Debian bookworm since buster is years out of
support and lacks python 3.8 needed by newer node-gyp.

- [x] Confirm this fixes pnpm 9 upgrade via
#23546 (I had to test
this manually since CI got throttled, but the fix was confirmed)
- [x] Add this docker images to the CI machine image to avoid
downloading it every run.
