tt in `configure-qiskit-local` (#1430)

There are some very small formatting issues in
https://docs.quantum.ibm.com/start/configure-qiskit-local . Nothing
terrible, it was just easy to fix than to report them.

 - `circuit_mpl_style_path`: The paths to have the circuit drawer use to look for JSON style sheets when using the mpl output mode.
 - `state_drawer`: This is used to change the default system for the state visualization draw methods. Valid values are `repr`, `text`, `latex`, `latex_source`, `qsphere`, `hinton`, or `bloch`. When the output kwarg is not explicitly set on the [qiskit.quantum_info.DensityMatrix.draw](../api/qiskit/qiskit.quantum_info.DensityMatrix#densitymatrix) method, the specified output method is used.
 - `transpile_optimization_level`: Change the default optimization level for [qiskit.compiler.transpile](../api/qiskit/compiler#circuit-and-pulse-compilation-functions). Specify an integer 0-3.
-- `parallel`: Whether Python multiprocessing is enabled for operations that support running in parallel.  For example, transpilation of multiple [qiskit.circuit.QuantumCircuit](../api/qiskit/qiskit.circuit.QuantumCircuit#quantumcircuit-class) objects. This setting can be overridden by the QISKIT_PARALLEL environment variable. Specify a boolean value.

 Set these environment variables to alter the default behavior of Qiskit:
 
-- QISKIT_PARALLEL: Enables Python multiprocessing to parallelize certain operations; for example, transpilation over multiple circuits in Qiskit. Specify a boolean value.
+- `QISKIT_PARALLEL`: Enables Python multiprocessing to parallelize certain operations; for example, transpilation over multiple circuits in Qiskit. Specify a boolean value.

+- `QISKIT_NUM_PROCS`: The maximum number of parallel processes to launch for parallel operations if parallel execution is enabled. Specify an integer greater than zero.
-- RAYON_NUM_THREADS: The number of threads to run multithreaded operations in Qiskit. By default, multithreaded code launches a thread for each logical CPU. To adjust the number of threads Qiskit uses, set this to an integer value. For example, setting RAYON_NUM_THREADS=4 launches four threads for multithreaded functions. 
+- `RAYON_NUM_THREADS`: The number of threads to run multithreaded operations in Qiskit. By default, multithreaded code launches a thread for each logical CPU. To adjust the number of threads Qiskit uses, set this to an integer value. For example, setting RAYON_NUM_THREADS=4 launches four threads for multithreaded functions. 
-- QISKIT_FORCE_THREADS: Specifies that multithreaded code should always execute in multiple threads. By default, if you're running multithreaded code in a section of Qiskit that is already running in parallel processes, Qiskit does not launch multiple threads but instead executes that function serially. This is done to avoid potentially overloading limited CPU resources. However, if you want to force the use of multiple threads even when in a multiprocess context, set QISKIT_FORCE_THREADS=TRUE.
