Update bats tests to add the "release" tag

[julienloizelet]

Since https://github.com/ddev/github-action-add-on-test/releases/tag/v2.1.0, user can exclude "release" tagged tests from pull request workflow.

As it is the default expected behavior, we should update the bats tests accordingly (here):

# bats test_tags=release
@test "install from release" {
...
...
}
