Welcome page for new project does not propose HTTPS for git

The welcome page for a new empty project (without README) give commands to create a new git project or push an already existing project. However these instructions are not provided for HTTPS, slowing down the workflow for people that are not able to use SSH (e.g. firewall).

A proposition for a fix would be to add a dropdown allowing users to switch the view between SSH and HTTPS, similar to the one existing for cloning projects:

Information on how to create a PAT and relevant links could also be provided for 2FA users.
