ws-transport sets unconfigurable 120000ms timeout, breaking long running `execStream`

Line 313 in 9908a8b

const timeoutMs = this.config.requestTimeoutMs ?? 120000;

The timeout for the WS transport is set at 2 minutes.
This means if you run a process via execStream in the Sandbox, and it takes over 2 minutes (streaming from an agent, for example), the stream dies with an unhandled error timeout after 120000ms.

This also appears to be an issue when I start a process as a background process, and then connect to its log stream, presumably same code path.

Suggestion: allow this to be configurable in wrangler file and document that the default is only 2mins.
alternatively, if I'm missing something let me know!

Thank you! I will take a test drive this evening, just been randomized onto some less fun work for a bit.
