Subject: [PATCH] REST API: Add `gmt_offset` and `timezone_string` to the base
 `/wp-json` response.

The site's current timezone offset is an important piece of information for any REST API client that needs to manipulate dates.  It has not been previously available.

Expose both the `gmt_offset` (the site's current offset from UTC in hours) and `timezone_string` (which also provides information about daylight savings time) via the "site info" endpoint (the base `/wp-json` response).

Also update the `wp-api-generated.js` fixture file with the changes to the default API responses.

Props sagarkbhatt.
Fixes #39854.
