mega-linter-runner --install generates invalid Github Actions workflow

[sammcj]

Describe the bug

npx mega-linter-runner --install adds invalid characters to the generated Github Actions workflow yaml, resulting in Github rejecting the workflow.

Examples:

https://github.com/sammcj/sqs-message-action/actions/runs/2750875544/workflow#L43

To Reproduce
Steps to reproduce the behavior:

1. npx mega-linter-runner --install

? What is your project type ? Let MegaLinter suggest to me later (recommended)
? What CI/CD system do you use ? GitHub Actions
? Do you want to detect excessive copy-pastes ? No
? Do you want to detect spelling mistakes ? No
? Which MegaLinter version do you want to use ? v6 (Latest official release)
? What is the name of your repository default branch ? main
? Do you want MegaLinter to validate all source code or only updated one ? Validate only sources diff with master/main branch
? Do you want to automatically apply formatting and auto-fixes (--fix option of linters) ? Yes
? Do you want MegaLinter to upload reports on file.io ? (report is deleted after being downloaded once) No
? Do you want to see elapsed time by linter in logs ? Yes
? Do you want to connect to OX Security to secure your repository ? No

3. Open .github/workflows/mega-linter.yml
4. See invalid characters on line 43

Expected behavior

No invalid characters / a working workflow

Screenshots

I believe what should be generated was:

 VALIDATE_ALL_CODEBASE: ${{ (github.event_name == 'push') && (github.ref == 'refs/heads/main') }}

Additional context

• macOS 12.5
