URL getters (etc.) now returning ArrayBufferView and not string

[Cherry]

In the latest workers-types release, some return types are being typed as ArrayBufferView instead of string, such as the getters on URL objects.

Reference: https://npmdiff.dev/@cloudflare%2fworkers-types/4.20240222.0/4.20240312.0/package/2023-07-01/index.d.ts/

Previously worked:

export default {
	async fetch(request: Request, env: Env, ctx: ExecutionContext): Promise<Response> {
		const url = new URL(request.url);
		const urlWithHostname = url.hostname + url.pathname;
		return new Response(urlWithHostname);
	},
};

Now it errors with:
Operator '+' cannot be applied to types 'ArrayBufferView' and 'ArrayBufferView'.ts(2365)

This also impacts getters on URLSearchParams. I would guess these unintentional changes are due to some of the changes with ada url implementation, but I'm not confident.
