Use `out_eia__yearly_generators` to work with recent PUDL releases

[zaneselvans]

Hey, I don't know how actively y'all are using this repo but I wanted to note that you're referring to a table _out_eia__yearly_generators that was removed a few releases ago. In newer releases the same data can be found in out_eia__yearly_generators. It shows up in both utils/pudl.py and utils/table_map.py

In our S3 usage metrics we see that somebody out there is still relying on it pretty heavily, and accessing it from a Microsoft IP address (so maybe GitHub actions?) and just wanted to see if we could get folks pointed at the fresher data. You might want to compare any table names you're referencing directly with the PUDL Data Dictionary just to make sure they're still available.

You can also list all the Parquet outputs in the most recent nightly build with something like...

gcloud storage ls -l --readable-sizes "s3://pudl.catalyst.coop/nightly/*.parquet"

to make sure the table you're using is there.
