solana: Validation of the new spl metadata account

[tokenwrap]

Problem: Attestation is failing for tokens that were created recently.

Cause: Metaplex has resized the SPL token metadata account from 679 bytes to 607 bytes in the commit (6b2e869) However, the token-bridge is still using the older version of the SPL token metadata and validating the size based on the older constant. As a result, this check fails to attest tokens that are using the new metadata accounts.

Solution: To resolve this, I have added an additional condition with the new metadata length constant, allowing the validation to pass if the SPL token has either of the two metadata account lengths.

Hi team any news @kcsongor @a5-pickle @johnsaigle

Bumping this here as well. No new token with metadata can be bridged out with Wormhole as of now.

FYI, https://github.com/wormhole-foundation/wormhole/issues/4478

so now there is no option to bridge new token? is there any workaround?
