WebTransport ignores query parameters in URL

[weary-adventurer]

Describe the bug
The final WebTransport URL doesn't include the query parameters from the original URL.

To Reproduce

engine.io-client 6.6.4

Client

// Connects to: https://localhost:1234/engine.io/?x=y&EIO=4&transport=polling&t=zsyh7czl 
eio("https://localhost:1234/?x=y", {transports: ["polling"]});

// Connects to: wss://localhost:1234/engine.io/?x=y&EIO=4&transport=websocket
eio("https://localhost:1234/?x=y", {transports: ["websocket"]});

// Connects to: https://localhost:1234/engine.io/
eio("https://localhost:1234/?x=y", {transports: ["webtransport"]});

Expected behavior
The WebTransport transport should preserve the query parameters in the same way other transports do.

Additional context

WebTransport currently uses createUri to construct the URL:

socket.io/packages/engine.io-client/lib/transports/webtransport.ts

Lines 31 to 34 in 439a8f6

	this._transport = new WebTransport(
	this.createUri("https"),
	this.opts.transportOptions[this.name],
	);

It doesn't include the original query parameters:

socket.io/packages/engine.io-client/lib/transport.ts

Lines 176 to 185 in 439a8f6

	protected createUri(schema: string, query: Record<string, unknown> = {}) {
	return (
	schema +
	"://" +
	this._hostname() +
	this._port() +
	this.opts.path +
	this._query(query)
	);
	}
