test(opencode): update tool parameter snapshots and assertions for schema changes

Refresh JSON Schema snapshots and adjust unit tests to reflect recent
schema modifications in the opencode tool definitions.

- Mark bash `description` field as optional and update its prefix text
- Add i18n key fields (headerKey, questionKey, labelKey, descriptionKey)
  to the question tool snapshot
- Flip bash parameter test from rejecting to accepting missing description
- Remove stale blank line in snapshot file
