matrix.org: Explained 'timeout' Parameter Is Missing in the Code Example.

I hope I'm correct here about reporting errors in the intro docs on the main matrix.org website, if not then I'm sorry in advance.

**Link to problem area**:
https://www.matrix.org/docs/guides/client-server-api#getting-live-state

**Issue**
_What is wrong?_

The section "Getting live state" under the above link mentions a `timeout` parameter one should apply. But the following code snippet that is supposed to demonstrate the use of that `timeout` parameter doesn't actually have the parameter in the used URL for the cURL command.

**Expected behaviour**
_How can the issue be fixed? Links to implementations/documents which prove the spec is wrong are appreciated._

Add the missing timeout=somevalue argument to the URL in the code snippet.

Open the linked matrix.org Client-Server API guide and find the “Getting live state” section and its cURL code snippet. Update the example URL to include a timeout=somevalue argument, then verify that the snippet matches the surrounding explanation.
