Subject: [PATCH] Replace typed-rest-client with global fetch

typed-rest-client was only used by PublicGalleryAPI, so it can go now
that Node 22 has a built-in fetch.

Keep the 'vsce' User-Agent that HttpClient('vsce') used to send, and
add a status check: a non-2xx response now throws with the gallery's
error message, or the HTTP status if there isn't one. Before, it
surfaced as an unclear JSON parse error.
