Explain how to list all catalogs using astroquery >=0.4.11 #215
Description
The default behavior of Irsa.list_catalogs() changed in astroquery v0.4.11 such that it no longer outputs image metadata tables, only catalogs. There is a new kwarg that can be used to get the old default behavior, include_metadata_tables=True. This causes a bit of trouble for our Euclid notebooks, many of which use that function to show all the Euclid tables. Trouble is that 25/26 of the Euclid tables are "metadata" tables, so users with astroquery >=0.4.11 don't see them and it's confusing. Unfortunately, include_metadata_tables is a new kwarg, so we can't just add that to the notebooks because it will error for users with <0.4.11. Probably the best we can do is to add a code comment to those cells telling people that if they only see one catalog output then they should add the kwarg include_metadata_tables=True to see all of them.
