App appends `:5000` to the name of a socket file.

[mike-matera]

When I try to run my app over a UNIX socket it seems that Quart appends a bogus port number to the socket name. For example:

quart run --host=unix:///$(pwd)/fun.sock

Results in the file fun.sock:5000. Running the exact same app in Flask results in the correct filename, which should be fun.sock.

Environment:

• Python version: 3.12
• Quart version: 0.20.0
