### Description of the change
This PR adds support for gpg key setup. It allows to pass the gpg private key content inline inside `values.yaml` or refer to an existing secret containing the key content data.
### Benefits
Administrators don't need to manually setup the gpg environment from inside a running container. It also eliminates the breaking change of Gitea 1.17 regarding `[git].HOME` as the `GNUPGHOME` environment variable is used consistently to relocate the `.gnupg` directory to its former location.
### Applicable issues
- fixes#107
### Additional information
This PR add the first unit tests to this Helm Chart, ensuring templating integrity for signing related configuration.
### Checklist
- [x] Parameters are documented in the `values.yaml` and added to the `README.md` using [readme-generator-for-helm](https://github.com/bitnami-labs/readme-generator-for-helm)

With release 5.0.0 there are so many deprecations and breaking changes
that it is probably a good way to assist the users with values migration
before breaking their environments.
This adds another template file that doesn't render anything but ensures
the removal of dropped or deprecated settings from customized values
files.
For when it is necessary, this check can be disabled via new setting
`checkDeprecation`.
