Backport test container versioning to release branches #2213

Release branches for 0.3 and 0.4 are currently broken due to the test containers changing the vi/vim versions used and causing them to issue events the tests don't expect to get.

This was fixed on the main branch by #1782 and #2209, we need to backport these fixes in a way that will not cause the release branches to rebuild the tests containers themselves.
