Update make-docs procedure (#70265)

## 4.1.0 (2023-06-16)

### Added

- Mounts of `layouts` and `config` directories for the `website` project.
  Ensures that local changes to mounts or shortcodes are reflected in the development server.

### Fixed

- Version inference for versioned docs pages.
  Pages in versioned projects now have the `versioned: true` front matter set to ensure that "version" in $.Page.Scratch is set on builds.

## 4.0.0 (2023-06-06)

### Removed

- `doc-validator/%` target.
  The behavior of the target was not as described.
  Instead, to limit `doc-validator` to only specific files, refer to https://grafana.com/docs/writers-toolkit/writing-guide/tooling-and-workflows/validate-technical-documentation/#run-on-specific-files.

## 3.0.0 (2023-05-18)

### Fixed

- Compatibility with the updated Make targets in the `website` repository.
  `docs` now runs this script itself, `server-docs` builds the site with the `docs` Hugo environment.
