[SW-218309][CI] Changed How Synapse Version Is Calculated For Tests (#958)

Changed how Synapse version is calculated for tests.

If the base branch of the PR is a release version, it will use the
release version, for any other base branch it will use the same version
as in habana_main which is the latest released one.
