romancal mosaic pipeline documentation issues

[stscijgbot-rstdms]

Issue RCAL-890 was created on JIRA by Samantha Hoffmann:

The mosaic level pipeline page on readthedocs (https://roman-pipeline.readthedocs.io/en/latest/roman/pipeline/mosaic_pipeline.html)) only briefly mentions the source catalog step in the table, and does not mention the flux step at all. Right now there's no documentation I could find that lets users know the flux step is part of the mosaic pipeline.

Additionally, the docstring for the mosaic pipeline class ([https://github.com/spacetelescope/romancal/blob/main/romancal/pipeline/mosaic_pipeline.py]) does not list source catalog or flux in the list of steps the pipeline runs.

(Side note: this is my first time attempting to create an issue for romancal documentation, so it's highly likely I have made a misstep somewhere. Information on how to file issues like this correctly is very welcome, thank you in advance for your patience!)
