Switch from jose to cloudflare-worker-jwt

[Skaldebane]

I've had many issues with fireworkers with Cloudflare Pages (in a SvelteKit project).

At build time (on deployment), the build fails due to lack of CryptoKey, which is extremely weird.

However, I found a workaround inspired by panva/jose#411 (not included in this PR), by polyfilling CryptoKey from @peculiar/webcrypto before calling Fireworkers.init(...).

import { CryptoKey } from "@peculiar/webcrypto";
globalThis.CryptoKey = CryptoKey;

However, this fix only works when using @tsndr/cloudflare-worker-jwt, while jose complains about CryptoKey not being the same as the one it expects.

I'm currently using this version in a real app and it works flawlessly.

While jose should normally work just fine on any environment, cloudflare-worker-jwt is a pretty solid replacement, especially that fireworkers is targeting Cloudflare Workers specifically.

Maybe I'm missing something here, so it's okay if you refuse this change!

I just updated the jose dependency version from 4.11.2 to 5.9.6 in #42. Can you let me know if after this upgrade the issue still persists? If yes, I'll merge this PR.
