Publish badges to GitLab Pages for correct mime type when serving.

In reference to the .htaccess redirect workaround suggested in fdroid-website#107 (closed), I figured out that the .svg images served from /raw URLs on GitLab don't come with the correct mime types, and thus are served as plain text and not rendered correctly if used in an <img /> tag.

This publishes them to https://fdroid.gitlab.io/artwork/badge/get-it-on.svg using GitLab CI.

merged

@eighthave, @mvdan - could one of you please either: Bump my status in this repo to "Owner", or enable Pipelines (or CI/CD - whatever GitLab calls it in the settings page). That is required for this MR to work. Cheers.

You're already set to Master, and the UI doesn't provide Owner as an option to set your account to

Looks like a new feature: Pipelines is now disabled by default, and I had to enable it.

I manually triggered a build, but it didn't seem to deploy it: https://gitlab.com/fdroid/artwork/pipelines

Ok, it finally deployed, though there is one errant failure: https://gitlab.com/fdroid/artwork/pipelines/12117455/builds
