* ci(fix): Temporarily avoid specifying `provenance`
As the test workflow does not use the `docker-container` buildx driver, it uses the Docker Engine bundled BuildKit version which until v23 release does not support attestations.
Likewise the current buildx version in CI is `0.10.0` which does not respect `--provenance false`, the presence of the option appears to trigger a BuildKit version compatibility check and fail early before it considers the value of the option.
* chore: Use buildx `docker-container` driver instead
An alternative solution to omitting `provenance: false` (_not supported by buildx 0.10.0 with default `docker` driver when Docker Engine bundles BuildKit less than 0.10.0, which is the case prior to the Docker Engine v23 release_).
This approach provides more consistency with the build and publish workflows by using the same buildx `docker-container` driver (_and thus newer BuildKit, enabling support for `provenance: false`_).
* chore: Revise test workflow inline docs
Buildx `docker-container` driver is not needed here, but it does seem like it improves cache-hit ratio when building from the retrieved build cache (from the earlier build workflow). Possibly due to building with the same BuildKit version.
These updates support running tests that have been relocated into `serial` and `parallel/set*` directories.
- `make tests` now calls the two make targets beneath it. The only difference is that `serial` continues the "1 test at a time" approach used prior to this PR, while the `parallel` target increases the `--jobs` arg to run multiple tests concurrently (_configured by `PARALLEL_JOBS`_).
- The `test/%` target leverages Bash syntax magic to ease running single tests without providing the exact path.
- This syntax also supports providing multiple test names (eg: `make test/clamav,template`) to run.
- `**` (globstar) allows for future improvements that can group multiple test files into sub-directories by their scope (eg: anti-spam, ssl, etc).

chore: Add `shopt -s globstar` to other targets
I realized that other targets should have this as well in case it is not set.
It is better to be more explicit here than to have weird errors due to `**` not expanding properly.

fix(Makefile): Add back `.PHONY` targets
I encountered `make` telling me the target was already up-to-date, which of course is nonsense.
I therefore added back the `.PHONY` targets to ensure tests are always run.

docs: Added instructions for running a single test
See https://github.com/docker-mailserver/docker-mailserver/pull/2857/files#r1008582760
The build arguments `VCS_REF` and `VCS_VER` were renamed and given
proper values according to their names.
1. `VCS_REVISION` holds the current SHA sum of the (git) HEAD pointer
2. `VCS_VERSION` now holds the contents of the `VERSION` file, i.e. a
semver version tag (one can now inspect the image and find a proper
version tag in the `org.opencontainers.image.version` label)
The build arguments were given defaults in order to allow the
`generic_build` and `generic_test` workflows to omit them (as they are
not need there anyways). When publishing images, this is fina as the
cache will rebuild almost all of the image except the last few layers
which are `LABEL`s anyways.
Mew re-usable workflows are introduced to handle building, testing and publishing the container
image in a uniform and easy way. Now, the `scheduled_builds`, `default_on_push`
and a part of the `test_merge_requests` workflow can use the same code
for building, testing and publishing the container images. This is DRY.
