node:crypto — hash.digest('base64'|'base64url') ignores the encoding

[proggeramlug]

createHash(alg).update(d).digest('base64'/'base64url') returns the hex string instead of base64. The digest codegen chain (crates/perry-codegen/src/expr/calls.rs) handles hex + no-arg Buffer only. Repro: node-suite/crypto/hash/digest-base64. Part of #793.
