New FAQ page on regulation and cis-regulatory tracks, refs #24610

Adds FAQ/FAQregulation.html, the page requested in this ticket since 2019:
where to find transcription factor binding site data, and how the various
cis-regulatory tracks relate to each other.

The page is organized around the measured vs predicted distinction, which is
what most of the mailing list questions turn on, and then covers which TFBS
tracks to use, what to do when a factor is in none of them, loading ENCODE
portal data through the portal's own Visualize button, promoters, enhancers,
cCREs, restricting to a cell type, and working outward from a gene. It ends
with a summary table of 16 tracks.

Assembly coverage is given per track and every assembly name is a link to
that track's description page on that assembly, since coverage varies a lot
(mm39 carries only three of these tracks, and TFBS Conserved was never built
for hg38).

Also adds the category to FAQ/index.html and a cross-link from the promoter
sequence question in FAQ/FAQdownloads.html.
