fix(ansible): Résolution violations linting YAML

Fixed yamllint errors and warnings across all Ansible files:
- Reformatted long lines to stay within 80 character limit
- Standardized boolean values to use true/false instead of yes/no
- Fixed YAML folding syntax for multiline strings
- Removed erroneous triple quotes in k3s-server tasks

This resolves all yamllint issues reported by the CI pipeline.
