Requirements:

Add the ability to bulk delete repositories for the "My repositories" page.

Selections boxes (see attachments) will be found in the left most column of each repository. 

And a "Kebab" (see attached image) should be added with the option to "Remove All" 

Optionally, we could have this button (and the add content button on smaller screens) only shrink to the kebab when insufficient space is given.

Considerations: 

• As the list api is paginated, we should think through how we would make multi-page selections for deletion. 
• What if someone in the same org deletes a repository before you, and you attempt to bulk delete, would a "not found" error revert all?
