Nest the TSS tracks on alpha only, leaving the release as it is. refs #35528

PRO-cap and ProCapNet sit inside a transcriptionStart superTrack on alpha. That
needs #38460, which is on master but not in a release, and these tracks are
already released, so each source is written twice with complementary release
tags: the nested copy alpha, the flat copy beta,public. hgTrackDb takes the copy
whose release matches and rejects two whose releases overlap.

Verified that beta and public are untouched: a public build from this file is
byte-identical to a public build from the released flat tree, same md5 over
tableName, shortLabel, type, visibility, priority and settings. tdbQuery -check
-strict passes on all three releases, and an alpha build has the container with
both members parented while beta and public have neither.

Drop the release tags and the flat copies once #38460 ships.

The makedocs also record that the alpha build needs hgTrackDb and trackDbToTxt
in /cluster/bin/x86_64 to carry the #38460 fix. make alpha does not install
there, BINDIR defaults to ~/bin/$MACHTYPE, so they were put in by hand and the
weekly utils build will overwrite them.
