Ajax fetch and fetchJson method doesn't use params property

[Velorexe]

Expected behavior

Using the exported fetch and fetchJson methods with a param property in the init object should result in the passed parameters to show up as query parameters in the URL.

const resp = await ajax.fetch('/example/', { params: { query: 'param' } } );

Actual Behavior

The example above results in a request made to /example without any query parameters.

The fetch and fetchJson method exported from the Ajax method doesn't use the params property that's passed through the init parameter. The property is set to the Request object that's created, but the native fetch method in the browser doesn't use the property (neither is it in the documentation for a Request object).

Here's how it's currently implemented in the Ajax class.

  async fetch(info, init, parseErrorResponse = false) {
    const request = /** @type {CacheRequest} */ (new Request(info, { ...init }));
    request.cacheOptions = init?.cacheOptions;
    request.params = init?.params;

In the cacheManager class there's mention of a stringifySearchParams method, but it isn't called when a request is made or intercepted.
