chore(core): refactor to make all unit tests pass (#6)

_This is the first time I ever messed with helm and is an experiment to show what prevents the tests to pass and how far it still depends on the gitea chart_
### Description of the change

- Deletes a single test that seems to depend directly on gitea
- make all tests pass
- Moves all value accesses from `actions` one level up
- Copies content of the gitea chart required by the existing test
  - Reveals all dependencies that needs to be decoupled
- Fixes readme generation
  - add package.json
  - copy dependent readme section from helm-gitea
- Removes all dependencies
- giteaRootURL is now required to be provided
  - consistency check that this value has been provided
  - added test for consistency failure
- nc command no longer uses an hardcoded dns name and is checked in tests
  - added test
- Copied yamllint from helm-gitea
  - added pnpm lock file exclusion
- Installed pnpm in the workflow
- Updated make unittest command in CI to unittest-helm
### Benefits

The existing tests are passing

### Possible drawbacks

The provision job might still not work.

### Applicable issues

- Fixes #5

### Additional information

The following usage should now deploy
```yaml
existingSecret: "somesecret"
existingSecretKey: "key"

## Specify the root URL of the Gitea instance
giteaRootURL: "http://somedomain:3000"
```
### ⚠ BREAKING

- giteaRootURL is now required to be provided
- Moves all value accesses from `actions` one level up
  - The values.yml had this change without updating tests / dev Readme
