Adds more granular TypeScript operation type literals for the various “revoke * sponsorship” helpers, and exercises them via new type-level tests.

Changes:

• Added distinct OperationType.* string literal types for each revoke-sponsorship helper
• Updated revoke-sponsorship operation interfaces to use those more specific discriminant type values
• Added type tests asserting Operation.fromXDRObject(...) returns operations with the new specific .type literals
