Minor change: Add edit profile button onto self user card

All this does is checks if the profile belongs to you, and if so, adds a link that opens your profile settings

I think this improves workflow and addresses how new pleroma users constantly ask me "Wait how do I edit my profile" because they're looking for this feature to be there and not finding it.

Tested working with develop branch via npm run dev (screenshot taken on Disqordia.space)
