fix(rebase-snap): Move deprecation message

Commit ded9038 ("deprecation(rebase-snap): marked rebase-snap as
deprecated") breaks our release process, because it shows the
deprecation message before the version info and the release script
gets the version from the first line. This commit moves the deprecation
message not to come before the version info.
