Help pages: fix broken internal links and restore anchors people still cite, refs #38062

Three groups of anchor problems on the help and FAQ pages.

Broken internal links, five pages: posters.html listed a 2022 section that
does not exist (no 2022 posters), api.html listed REST and JSON separately
after the two sections were merged, docker.html pointed at a #UsrAcct section
that is not on that page, FAQgenes.html had a capitalized #ncbiRefSeq where
the anchor is #ncbiRefseq, and the genomes.txt settings rows in
trackDbHub.v3.html carried no anchors so its own "genome" link missed.

Retired anchors that are still cited in twenty years of answers on the genome
list. Content moved to its own page and the old anchor was deleted rather than
left behind, so the citations land at the top of the page. Reattached seven
numeric FAQformat anchors to the Topics entry linking to each format's page.
BED, PSL, GFF and GTF were removed from the custom track page in 2012 and
never added back to its list of supported formats; added them with the old
anchors, which fixes customTrack.html and hgTracksHelp.html together since
both include customTrackText.html. Also restored #lines there, and #Session
on hgTrackHubHelp.html and #link4 on FAQlink.html.

Section anchors on six pages that had none, so a support answer can link to
one part of them: bam.html, hic.html, bedgraph.html, ftp.html, net.html and
trackDbIndexBb.html. Skipped quickLiftChain.html, oligoMatch.html and
cutters.html, which are track description fragments included into the details
page rather than standalone pages.
