0.2.0-dev4: Fix problem when adding an element on the index 0 of a list

This problem happened when the list doesn't exist on the original yaml.
In this situation, the new element was added as a dictionary of key "0".
Now, with the current fix, the list is properly created and the element
is added as a normal list element.

Apart from that, we've commented the step that pushes the self-contained
package to the release since we need to enable first
"softprops/action-gh-release@v2".

0.2.0-dev3: Building a self-contained package

The generic-k8s-webhook can now be packaged into a self-contained
package, so this package can be executed without the need of installing
any extra dependency. To do so, we're leveraging pyinstaller.

Now, when we'll build a new release, we'll push this self-contained
package as part of the release.

Full Changelog: 0.1.0...0.2.0-dev1

0.1.0

Create workflow to build the Docker image on any branch

The Docker image will be build on any branch, to ensure the healthiness
of this process. Apart from that, the "build_and_release" job will only
be executed when we create a new tag in the repo.

0.1.0-dev1

Inject git tag in the pyproject.toml file as the package version

This helps us having a single source of truth for the versions, which
is the git tag. This git tag is inserted to the pyproject.toml file,
in the version field, as part of the job that builds and pushes the
docker image when a new release is created.

v0.1.0-alpha

First alpha release of the project
