support of crossorigin="use-credentials" for basic auth

[flkrnr]

Thanks for your awesome work so far!

It would be great if we could have support for applications behind basic auth.

I think this should be possible by simply adding crossorigin: 'use-credentials' to the manifest.json link:

nuxt-pwa-module/src/parts/manifest/index.ts

Lines 29 to 32 in bdd4b4f

	pwa._manifestMeta = {
	rel: 'manifest',
	href: joinURL(nuxt.options.app.baseURL, 'manifest.json'),
	}

(Souce: https://developer.mozilla.org/en-US/docs/Web/HTML/Attributes/crossorigin)

as far as i can tell it is possible in the pwa-module for nuxt2. (https://pwa.nuxtjs.org/workbox#basic-auth)

relates to #54

Closed by #55

Will be available in next release

@kevinmarrec i think this needs to be implemented as well when loading the manifest.json (see my reference) #55 just adds interface definitions for other properties but not the property crossorigin nor the actual implementation.
