Subject: [PATCH] feat(traefik): add option to skip YAML validation for Go
 templating

- Introduced a checkbox to skip YAML validation in both the UpdateTraefikConfig and ShowTraefikFile components, allowing users to save configurations that utilize Go templating.
- Updated the onSubmit logic to conditionally validate YAML based on the new checkbox state, enhancing flexibility for users working with dynamic configurations.
