Issue DM-4649: Create and rename the sims_dustmaps repository to sims_maps
Create and rename the sims_dustmaps repository to sims_maps. This is my plan after talking to [~jhoblitt]: Add sims_maps to {{lsst_build/repos.yml}}. Change related dependencies and create ticket branches, run CI to confirm the changes.
