Add yamllint hook to .pre-commit-config.yaml to standardize YAML files
across the project. Created .yamllint.yml configuration with relaxed
rules to accommodate existing files. Fixed colon spacing in .asf.yaml
to pass yamllint checks.

Closes #10974

- Remove extensive file exclusions, keep only k8s templates
- Increase line length limit to 400 chars (GitHub Actions friendly)
- Allow flexible colon spacing (max-spaces-after: -1)
- Disable document-start requirement

This provides linting value while handling infrastructure patterns.
