Put PRO-cap and ProCapNet inside a Transcription Initiation folder. refs #35528

The two data sources were top-level superTracks because a superTrack could not
be a member of another one. #38460 fixes that, so they now sit inside a
transcriptionStart superTrack, which is what the collection was meant to be.

The container is written before either of its children, and both children before
any of their members: tdbQuery -strict rejects a file in which another track
comes between a superTrack and one of its children.

This depends on the #38460 build. A plain make here with the installed binaries
produces a half-built state, since hgTrackDb drops the container from the table
and trackDbToTxt then writes an hs1 curated hub whose member names a parent
stanza that is not there. Both makedocs say so.
