[Enhancement] Add build variant to set router base

[crobibero]

  router: {
	[...]
    base: '/web/'
  },

This would allow jellyfin-server to host the generated static files in place of jellyfin-web

Edit: This also doesn't work if jellyfin is hosted under a baseurl

Edit many months later:

Setting the router.base field to ./ allows the ui to load, and only vue fonts and images fail to load
