feat(registry): add SPAKE2 (RFC 9382) and SPAKE2+ (RFC 9383) (CycloneDX#798)

## Summary
Add SPAKE2 (RFC 9382) and SPAKE2+ (RFC 9383) to
`schema/cryptography-defs.json`.

## References
- Issue: CycloneDX#797
- RFC 9382: https://doi.org/10.17487/RFC9382
- RFC 9383: https://doi.org/10.17487/RFC9383

## Change
- Add `family: SPAKE2` with variants:
  - `SPAKE2`
  - `SPAKE2[-{group}][-{hashFunction}][-{kdf}][-{mac}]`
- Add `family: SPAKE2PLUS` (represents SPAKE2+) with variants:
  - `SPAKE2+`
  - `SPAKE2+[-{group}][-{hashFunction}][-{kdf}][-{mac}]`

Notes:
- `family` uses `SPAKE2PLUS` (no `+`) to match existing registry naming
constraints, while `pattern` preserves the canonical protocol name
`SPAKE2+` from RFC 9383.
- Entries are placed in alphabetical order within `algorithms[]`.

## Validation
- `python3 -m json.tool schema/cryptography-defs.json` (JSON OK)
