spec: add translation_memory resource and missing v3/languages/resour…

[lilkraftwerk]

What

GET /v3/languages and GET /v3/languages/resources had drifted from the live API. This extends three enums to match what api.deepl.com actually returns:

• resource query parameter enum (/v3/languages): add translation_memory
• /v3/languages/resources resource-name enum: add translation_memory
• /v3/languages/resources feature-name enum: add transcription, translated_speech, spoken_terms, translation_memory

No API behavior change. This only aligns the published spec with the responses the live API already serves.

Evidence (live api.deepl.com)

translation_memory is a valid resource the current spec enum rejects:

$ curl '.../v3/languages?resource=translation_memory'
[
  { "lang": "de", "name": "German", "status": "stable",
    "usable_as_source": true, "usable_as_target": true, "features": {} },
  { "lang": "de-DE", "name": "German", "status": "stable",
    "usable_as_source": false, "usable_as_target": true, "features": {} },
  ...
]

/v3/languages/resources returns feature names not in the current enum (voice's spoken_terms / transcription / translated_speech, plus translation_memory as a resource):

$ curl '.../v3/languages/resources'
[
  ...
  { "name": "voice", "features": [
      { "name": "auto_detection",    "needs_source_support": true },
      { "name": "formality",         "needs_target_support": true },
      { "name": "glossary",          "needs_source_support": true, "needs_target_support": true },
      { "name": "spoken_terms",      "needs_source_support": true },
      { "name": "transcription",     "needs_source_support": true },
      { "name": "translated_speech", "needs_target_support": true }
  ] },
  { "name": "translation_memory", "features": [] }
]
