[Typescript] `browser.runtime.getURL` doesn't respect the unlisted css

[iyume]

Describe the bug

While npx wxt prepare generates the types folder, it doesn't generate types for browser.runtime.getURL for the unlisted css (documentation).

Also, i noticed that there is an error in the description of the documentation about unlisted css.
entrypoints/{name}.(css|scss|sass|less|styl|stylus) will generates /assets/{name}.css, not /{name}.css.

Reproduction

This is a reproduction to inject css file into main world.

/entrypoints/main-world.css is the target css file will be injected into the main world.

injectCss(browser.runtime.getURL('/assets/main-world.css'))
// injectCss just creates the link element and insert into document head

The generated types for the browser.runtime.getURL looks like:

declare module "wxt/browser" {
  export type PublicPath =
    | ""
    | "/"
    | "/background.js"
    | "/content-scripts/mycontent.js"
    | "/icons/128.png"
    | "/icons/16.png"
    | "/icons/32.png"
    | "/icons/48.png"
    | "/inject.js"
  type HtmlPublicPath = Extract<PublicPath, `${string}.html`>
  export interface WxtRuntime {
    getURL(path: PublicPath): string;
    getURL(path: `${HtmlPublicPath}${string}`): string;
  }
}

The unlisted script (inject.js) is properly generated, but unlisted css is not.

I read the source code related to wxt prepare and discovered some code that may cause this bug:

wxt/packages/wxt/src/core/utils/building/find-entrypoints.ts

Lines 109 to 115 in 4f772fc

	return await getContentScriptEntrypoint(info, options);
	case 'unlisted-page':
	return await getUnlistedPageEntrypoint(info, options);
	case 'unlisted-script':
	return await getUnlistedScriptEntrypoint(info, options);
	case 'content-script-style':
	return {

(If this is confirmed to be a bug, I can try to make some contributions if necessary.)

will generates /assets/{name}.css, not /{name}.css.

This part is not a bug.
As you can in these lines, it is intentionally set to assets folder.

But yeah, there seems to be types bug.

Edit: This is partly related to this PR #1590
