Rearrange Clone Panel (#31142)

Rearrange the clone panel to use less horizontal space.
The following changes have been made to achieve this:
- Moved everything into the dropdown menu
- Moved the HTTPS/SSH Switch to a separate line
- Moved the "Clone in VS Code"-Button up and added a divider
- Named the dropdown button "Code", added appropriate icon
