### Description of the change
This adds an environment for unit testing our bash scripts, using [BATS](https://github.com/bats-core/bats-core).
It implements first tests for `config_environment.sh`.
### Benefits
Writing unit tests for bash scripts documents the expected behavior and allows it being a quality gate in our CI.
### Possible drawbacks
Not everyone is familiar with this approach and unit testing framework. Me neither, it took me some hours to get into it.
### Applicable issues
- Related to #691 where an issue in `config_environment.sh` was detected. It doesn't fixes it yet. This will be a dedicated Pull Request.
### Additional information
I've verified that the changes for Renovate are indeed working.
You may wonder why there is only one `run $PROJECT_ROOT/scripts/init-containers/config/config_environment.sh` and many `run execute_test_script` calls.
Usually, testing a script itself would be executing `run $PROJECT_ROOT/scripts/init-containers/config/config_environment.sh`. You then can assert the exit code and other things. Since the `config_environment.sh` exports environment variables and we are not able to access them from outside a `run` execution, the function `execute_test_script` wraps our script execution between environment comparison. Doing so allows us capture environment variables that were added/removed during script execution.

### Description of the change
This is a preparation for #724 (bash script testing) which would be too complex to review if done there. I haven't changed the script contents.
### Benefits
Better IDE support, possibility for shell checks, tests.
### Possible drawbacks
-
### Additional information
I only extracted files that are native bash scripts. There are others, being a mix of Helm templating and shell scripts. Those scripts must be cleared first before extracting them as well.

While working on #409, I noticed that some unittests contains either
invalid assertion methods (`isNotEmpty`) or invalid properties (`any`)
for a specific assertion method (`notContains`).
As our tests pass - and I have ensured that they can fail - this seems
related to the YAML schema validation in the IDE.
I've noticed that `isNotEmpty` was replaced by `isNotNullOrEmpty`[^1]
in version v0.3.2[^2]. At least from a schema validation point of view.
It is still working. Maybe deprecated? I don't know.
Regarding the `any` property, the documentation seems incorrect. I've
filed a PR for it[^3]. As soon as that PR is merged and released, we
could probably validate the test YAML files in our PR workflow.
Last, since we renovate the used helm-unittest version, we should also
renovate the used YAML schema file.

### Description of the change
This adds a `.vscode` folder with recommended extensions and some useful settings like unittest schema validation.
The `.vscode` folder is already helm ignored during packaging.
### Possible drawbacks
We would have to be careful about PR changes in that directory.
