Auto-detected frameworks cannot use the static server

[ascorbic]

Describe the bug

If a framework has an entry in framework-info it disables the static server, meaning that any framework that needs this cannot use auto-detection, so misses out on the other benefits of auto-detection, such as build command.

To Reproduce
Cannot be reproduced because it would require adding a framework to framework-info, but the code is here:
https://github.com/netlify/cli/blob/main/src/utils/detect-server-settings.js#L260

This is related to #3654, and could be fixed with a similar solution to that, or more simply by starting the static server if the framework specifies no dev command and/or target port.

My comment here is relevant for this issue too

@ascorbic I opened netlify/framework-info#657.

Once we have that I think this issue will be about adding useStaticServer: true here

cli/src/utils/detect-server-settings.js

when a command/port is missing.
