Next/experimental release versions include commit date (#21700)

Change format of @next and @experimental release versions from <number>-<sha> to <number>-<sha>-<date> to make them more human readable. This format still preserves the ability for us to easily map a version number to the changes it contains, while also being able to more easily know at a glance how recent a release is.
