miladrahimi/php-jwt: Add Ed25519 and Ed448 support

[miladrahimi]

Updates the listing for miladrahimi/php-jwt to reflect the current state of the library as of v3.4.0, which adds the RFC 9864 fully-specified EdDSA algorithm names:

• Ed25519 → supported, added in v3.4.0 (Ed25519Signer, Ed25519Verifier) — same libsodium keys and signatures as the already-listed EdDSA, only the alg header differs
• Ed448 → supported, added in v3.4.0 (Ed448Signer, Ed448Verifier) — EdDSA over Curve448 via OpenSSL, with dedicated Ed448PrivateKey / Ed448PublicKey classes
• minimumVersion bumped 3.3.0 → 3.4.0 (the first release supporting the full matrix above)

Every other entry in the listing is unchanged and still accurate.

Verification:

• Signing and verification for both algorithms are covered by Ed25519Test and Ed448Test, plus cross-checks against externally generated tokens in InteropTest.
• The README documents both, and the runnable examples (examples/ed25519.php, examples/ed448.php) are themselves executed by the test suite.

Note on requirements, in case it matters for the listing: Ed25519 needs ext-sodium (as EdDSA already does), and Ed448 needs PHP 8.4+ for OpenSSL's Curve448 support — the key classes throw at construction otherwise. The ML-DSA entries are deliberately left false; the library does not implement them.
