The v3.0 provider is not yet available as a stable release in the
OpenTofu/Terraform registry. Downgraded to v2.9 which is the latest
stable version.
Also fixed minor yamllint issues in flux.yml:
- Added space after comment marker
- Removed trailing blank line
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.
