maintner/maintnerd/maintapi: adjust heuristic for tip version

The vast majority of the time, when Go 1.X (or Go 1.X.Y) is the latest
supported Go release, non-release branches are used for developing
the next Go 1.(X+1) version and not the same Go 1.X version.

Adjust the imperfect heuristic used to determine the Go version from
the branch name by taking this into account.

Make the output from the TestFindTryWork test easier to read,
as it's expensive to add test coverage for this change elsewhere.

For golang/go#42341.
Fixes golang/go#42377.
Updates golang/go#42376.
