Update gaia.rst with corrected hyperlinks

[hectorcanovas]

Dear Astropy/Astroquery team.

This is Héctor Cánovas, Support Archive Scientist of the Gaia ESA Archive (writing from my personal account). While inspecting the recently updated documentation of Astroquery.Gaia I noticed that there are 8 hyperlinks that miss the colon (:) symbol after the "https" preamble, and hence they do not work. This proposed version has updated these links as: https// >> https://

Thanks for fixing the urls, I'm afraid we don't have a good mechanism to fix these in a more automated way.

However the exact changes cause the docs build to fail, so some fixes are needed before this can be merged.

There are multiple TAP references (even in this same filee, but there maybe one already in the other docs files) so adding these breaks the docs build. Please either reuse the exising reference or use one-off links as before (albeit without the typo of course)

Thanks a lot for your help - now I am confused about how to proceed: should I create a new pull request from the Astroquery.Gaia documentation (https://astroquery.readthedocs.io/en/latest/gaia/gaia.html)? - this is how I created this pull request?

No, please keep working on in this PR rather than opening another.

We follow the typical fork based PR workflow wheere you have a local clone of the repo and edit files directly.
https://docs.astropy.org/en/latest/development/workflow/development_workflow.html

If you have edited it directly on github, you can still keep doing that, but in the long term that is much more limited and clumpsy (e.g. no way to run the tests locally, or make logical code chuncks into commits, etc.), but here it could still work:

Go to "Files changed", then choose "Edit" the file from the kebab menu.

RTD is passing now, so merging the PR.

Thanks @hectorcanovas and congrats on your first PR to astroquery!
