Subject: [PATCH] fix(deps): pin spl-token-group-interface to 0.7.1 for
 spl-token-2022 10.0.0

spl-token-group-interface 0.7.2 changed TokenGroup.update_authority to
MaybeNull<Pubkey>, while spl-token-2022 10.0.0 still expects
OptionalNonZeroPubkey, causing E0308 build failures. Pinning to 0.7.1
aligns transitive deps until upstream publishes a compatible release.
