STRchive track now updates itself, and is on hg19 and hs1 as well as hg38

STRchive builds a Genome Browser bigBed with every release now and publishes
it on their GitHub releases page, so there is nothing left for us to convert.
A new otto job checks weekly for a new release, downloads the file into its
own releases/<tag> directory, sanity-checks the locus count, and repoints the
/gbdb symlinks at it. Silent when there is no new release. See STRchive issue
333 for the correspondence that set this up.

Their releases carry hg19, hg38 and T2T-chm13 (= hs1) files and we take all
three, so the new strVar stanza lives in human/strVarNew.ra rather than under
hg38. The bigDataUrls use $D, and hgTrackDb -strict drops any member whose
file is missing, so each assembly gets only the tracks that were built for it:
STRchive on all three, the other four on hg38 only. The description page is
rewritten for the new evidence-level coloring, gains an evidence filter, and
now says that the track updates itself and that older versions are on GitHub
rather than here.

All of that is alpha only. Nothing copies /gbdb/*/strVar/ out to the RR yet,
so releasing this trackDb would have it promise data the RR does not have.
The old hg38-only version stays as human/hg38/strVar.ra, tagged beta,public,
until the sysadmins install the strchiveAutoPush cron drafted alongside the
otto job. The header of strVarNew.ra lists what to delete and rename then.
