Add Argon2 (RFC 9106) to Cryptography Registry (CycloneDX#793)

This PR adds Argon2 (RFC 9106) to `schema/cryptography-defs.json`.

## Notes on parameter naming vs Issue CycloneDX#756
Issue CycloneDX#756 proposes:
`Argon2(id|i|d)[-{memoryMiB}][-{iterations}][-{parallelism}]`.

RFC 9106 defines:
- `m` as **memory size in kibibytes (KiB)**,
- `t` as **number of passes**,
- `p` as **degree of parallelism**.

Accordingly, this PR uses:
`Argon2(id|i|d)[-{memoryKiB}][-{passes}][-{parallelism}]`

If the community prefers the Issue's naming for consistency with
existing conventions, I can update the pattern accordingly.
