feat(publish): a release keeps its colour, and a description for Explore

Publishing takes a description for Explore (rich text, as its JSON),
which Explore shows in place of the studyset's own: a studyset may
introduce itself to strangers otherwise than in the library, where its
author may leave it empty. Without one, as from older apps, the
studyset's description as before; one that isn't rich text, or over
100,000 characters, counts as none. A release also keeps the studyset's
colour, which Explore gives out with it; releases before have none. The
publication's releases say their description, for the next publish to
start from.

Migration release-colour adds a nullable column:
ALTER TABLE "studyset_release" ADD COLUMN "colorName" text;
the server before it reads and writes the table as ever.
