[BUG] Inconsistent `draw()` and `mpl_draw()` behavior

[ryanhill1]

There are inconsistent display issues when using pyqasm.draw() and pyqasm.printer.mpl_draw() in Jupyter notebooks:

pyqasm.draw() behavior:

• The circuit diagram displays correctly the first time it’s called.
• Subsequent calls produce no diagram output.
• Restarting the kernel resets this behavior — it works once and then fails on following calls.

pyqasm.printer.mpl_draw() behavior:

• The circuit diagram displays twice on the first call.
• Subsequent calls show the diagram only once, as expected.
• After restarting the kernel, the double-display issue repeats on the first call.
