Can someone who works on Android or at least works on Google help me get in contact with the right people?
There are a few issues with the Pixel 6a release which need to be resolved.
There are a few mistakes with the push to AOSP and also services that aren't set up properly.

We ended up getting in touch with a Google engineer who published the missing repository / tag and then we found a way to work around the Pixel 6a OEM unlocking issue so we don't really need help with this anymore. They should still prioritize fixing it but we'll be fine now.
