Allow Ctrl+V to paste new images into Wiki

Feature Description

When editing an issue comment, you can paste in new image attachments. It's a great low-friction way to make an issue more understandable, especially for screenshots.

It would be great to have this same capability to add images to Wiki documents.

Right now, you can only either (A) clone the git repo and add them manually, which is difficult for non-developer staff; or (B) create a dummy-issue for image uploads and copy the links into the wiki, which is a strange workaround

The underlying issue is, that images on issues and comments are stored in an attachment storage backend (local filesystem, s3, ...), and the data model for attachments currently does not support linking an attachment to a wiki page, so the logic of simple file uploads can not be trivially ported to the wiki.

This should be easy to extend, though we should consider whether it is good design to have images of the wiki stored externally to the wiki git repo, as it won't be selfcontained anymore.

to upload attachments with md file to same reposistory is useful.
pull all file to localhost and compile .md & images to html website

the wikis are just git repos, right? couldn't they store image files?

Yes, wikis are Git repos: #1426 (comment)

The whole idea is to allow non-tech staff to edit documentation in Wiki, add screenshots, other attachments etc.

Currently this is not possible because images need to be committed to main repository first and then its path referenced in Wiki.

This is related to #574.

It's duplicate of #574, as long as #574 could be done, there is no problem for Ctrl+V
