Fix documentation typos in record getters

Corrected typos and style inconsistencies in deprecated getter javadocs
to match the param documentation:

- MaxMind: "queried" → "queries"
- Subdivision.getConfidence(): "This is a value" → "A value"
- Subdivision.getIsoCode(): "contain" → "containing", "3166-2code" → "3166-2 code"
