Run constraint branch checkout in non-canary build (#35088)

The constraint branch checkout needs to happen always when there
is an "upgrade-to-newer-dependencies" build, not only wnen there
is a "canary" main build, Otherwise when we attempt to update to
diff constraints vs. the current ones the diff fails.

Only the Commit and Push which are the folowing steps should
happen exclusively in the canary run.
