Fix: correct gitlab url

.npmrc

 ; Set URL for your scoped packages.
 ; For example package with name `@coscine/bar` will use this URL for download
-@coscine:registry=https://gitlab.com/api/v4/packages/npm/
+@coscine:registry=https://git.rwth-aachen.de/api/v4/packages/npm/
 
 ; Add the OAuth token for the scoped packages URL. This will allow you to download
 ; `@coscine/` packages from private projects.
-//gitlab.com/api/v4/packages/npm/:_authToken=${NPM_TOKEN}
+//git.rwth-aachen.de/api/v4/packages/npm/:_authToken=${NPM_TOKEN}
 
 ; Add OAuth token for uploading to the registry. Replace <your_project_id>
 ; with the project you want your package to be uploaded to.
-//gitlab.com/api/v4/projects/26381/packages/npm/:_authToken=${NPM_TOKEN}
+//git.rwth-aachen.de/api/v4/projects/26381/packages/npm/:_authToken=${NPM_TOKEN}
