feat(preset): enable updating renovate in CI components

Nejc Habjanrequested to merge
nejc/renovate-runner:feat/ci-components-preset into main

GitLab CI components can be .yml files in templates/ or a single template.yml in templates/template-name/ directories, e.g.:

templates/renovate.yml
templates/renovate-config-validator.yml
templates/renovate/template.yml
templates/renovate-config-validator/template.yml

See https://docs.gitlab.com/ci/components/#directory-structure.
I kept this regex simple as I think the patterns matched are already very specific. (.yaml is also not officially documented so not sure if it's supported and I left it out on purpose).
