test: refresh conformance snapshot to Bot API 10.1

The committed botdoc snapshot was Bot API 5.3 (78 methods), making the
conformance drift-guard toothless against the modern surface. Refresh it to the
live published API (10.1, 180 methods) so the test enforces real parity.

Categorizes the 14 still-unimplemented published methods in deferredMethods,
each with the specific MTProto/td blocker (no exposed RPC or unmappable
semantics). All other published methods are now implemented or covered.
