[release/7.0.1xx] [maestro] Subscribe to the .NET 6 channel to get bumps for our own .NET 6 packages for .NET 7. (#16904)

We need the latest released version numbers for the previous .NET version so
that we can reference and consume those when building projects using the
corresponding target framework.

Luckily we have a system for keeping dependencies up-to-date, so let's use it
to notify the current branch for any updates to the release branch for the
previous .NET version.
