Support for `.mega-linter.yml` Base Config File Re-location

[comc]

The MEGALINTER_CONFIG environment variable should accept a relative path, e.g., .github/config/.mega-linter.yml, in order to re-locate the config file other than the project root, if so desired.

Currently, the variable only supports a standalone filename located in the repo root directory, or a remote URL.

@comc relative paths seems to work, several repos are using exactly what you want to do

Examples:

• https://github.com/ahmadnassri/action-dotenv/blob/master/docker-compose.yml
• https://github.com/ahmadnassri/action-semantic-release/blob/master/docker-compose.yml
• https://github.com/ahgraber/homelab-gitops-k3s/blob/main/.taskfiles/LintTasks.yaml
• https://github.com/recursion-ninja/personal-website/blob/35e18c45591b477cee963d741c9b93e27b961166/.github/workflows/haskell.yaml#L347

Is your repo public so i could check ?
