DOC: link to alma notebooks

[bsipocz]

Super nice notebooks, mostly using pyvo, but also one showcases astroquery, which look to be well maintained (and the 3 I've tried all work)

@bsipocz - where do you think we should link them from? ALMA documentation? Or is there a special astroquery section for these?

[bsipocz]

We don't yet have an astroquery section, but I think we should (at least once an overhaul of the landing page is done: #2555)

(I do really want to link out to the well-maintained and tested notebooks, e.g. ALMA, CDS, etc.)

In the meantime if you think it's useful, please do link out from the alma docs
