[Feature] GitLab kref for Netkan

[HebaruSan]

Netkan currently supports directly querying mods from GitHub with this format:

    "$kref": "#/ckan/github/HebaruSan/Astrogator",

The best known alternative to GitHub is GitLab. Currently I don't know of any KSP mods hosted on GitLab, but it could happen any day now. It would be nice if we could support it with something like:

    "$kref": "#/ckan/gitlab/HebaruSan/Astrogator",

GitLab's API docs are here:

• https://docs.gitlab.com/ee/api/README.html

Apparently they treat releases as just a kind of tag, like GitHub but even moreso:

• https://docs.gitlab.com/ee/workflow/releases.html

Looks like there may not be support for a discrete list of assets, since they show the download as a manually entered link in markdown. However, the example link goes to a relative link starting at /uploads/, so it looks like GitLab does support hosting releases.
