refactor(common): Use symlinks to state, which files should be replaced

Every symlink in the `./templates` directory is now replaced with
the file it points to, making it obvious that this file should not be
edited.

-    #   If auto_template is true then template is ignored and the SPDX

-    #   with licenses that have a standardLicenseHeader field defined in

-    #   licenseText to generate the header which works fine for short
-    #   licenses like MIT but can be quite lengthy for other licenses
-    #   like BSD-4-Clause. The above default template is valid for most
-    #   licenses and is recommended for MIT, and BSD licenses. Common
