Using `semantic-release` require the users to include
`templates/Semantic-release.yaml` and `extends` the `.semantic-release:*`
job templates.

We keep `templates/Release/Semantic-release.yaml` for backward
compatibility.

* templates/Semantic-release.yaml: new `semantic-release` related job
  templates

* templates/Lint/Commitlint.yaml: define `semantic-release` with the
  `.semantic-release:stable` job template for backward compatibility.
