updateSite ignores new values for session_id

[jimkyndemeyer]

Calling updateSite with a new session_id has not effect, and returns a site with the original session_id. The site's session_id is also unchanged on subsequent getSite calls.

Steps to reproduce:

In a js file:

import {NetlifyAPI} from "@netlify/api";

const api = new NetlifyAPI(process.env.NETLIFY_ADMIN_PAT);

const newSessionId = 'test';
const siteId = 'some-site-id';

(async () => {

    const updatedSite = await api.updateSite({
        siteId,
        body: {
            session_id: newSessionId
        }
    });

    if(updatedSite.session_id !== newSessionId) {
        throw new Error("API ignored new session id")
    }

})();
