fix: Re-enable 3 pulse control notebooks in test suite

Remove 2_Native_gate_calibrations, 3_Bell_pair_with_pulses_Rigetti,
and 4_Build_single_qubit_gates from EXCLUDED_NOTEBOOKS.

These were excluded with the comment 'does not converge due to device
quality' but pass with --mock-level=LEAST which uses real device
metadata. The Bell pair notebook frame name bug was fixed in #855.
