feat(registry): add scrypt (RFC7914) to Cryptography Registry (CycloneDX#784)

Adds `scrypt` (RFC7914) to the Cryptography Registry
(`schema/cryptography-defs.json`).

Rationale:
- RFC7914 specifies scrypt and it is commonly used for password hashing.
- This classifies `scrypt` under `primitive: "hash"` to remain
consistent with the existing registry taxonomy (e.g., `bcrypt`).

Closes CycloneDX#783
