[Webpack] Error overlay configuration

[sylvhama]

The overlay option for PreactRefreshPlugin is typed as a boolean in node_modules/@types/prefresh__webpack/index.d.ts

interface Options {
    overlay?: boolean;
    runsInNextJs?: boolean;
}

If I try to set it to true, an error will be thrown:

TypeError: The "request" argument must be of type string. Received undefined

Based on this PR: #289 ; I guess it expects an object with a module key, what should I pass there then?

Looks like indeed it needs a module key which should be typed as string | false.

You'd pass a path to a module to use as an error overlay when/if errors occur.
