Add gitlab logo to card attachments

We should add the gitlab logo to card attachments

mentioned in merge request !7 (merged)

perhaps a separate issue but would recommend also utilizing the card badge functionality with the GitLab logo. Enables users looking at a board to visually identify cards with GitLab attachments & number of merge requests/issues/etc.

Thats a good idea. Took me a while to understand the difference between card-badges and card-detail-badges since there were no visual examples in the docs. I created #23 (closed) to address your suggestion

I think it might be better to use attachment-sections like GitHub does with their PowerUp integration...

We'd have the GitLab logo in the section header instead of next to each individual attachment:
