Bump deprecation markers. (release-6.x)
Review Request #14983 — Created March 31, 2026 and submitted — Latest diff uploaded
We've decided to make what's currently in development as "Djblets 5.3"
be "Djblets 6.0", but we're not going to include any current deprecation
removals. This change bumps additional deprecation markers present on
the release-6.x branch.
Ran unit tests.
