Include NFS option in "Connect Server" menu

### Problem

Connecting to an NFS share is not super intuitive(to me) in current Elementary OS 6. Files makes it simple to connect to servers with various protocols but NFS is not an option.

### Proposal

I propose to include a NFS connection option in the Files application under the "Connect Server..." button in the lower left hand corner. The purpose of this being to improve access to NFS shares following the same approach communicated for SMB, FTP, SSH, AFP etc..

### Prior Art (Optional)
