Spelling Mistake in wordle/simulations.py

in wordle/simulations.py, line 455
original: `this gives the a lower boudn on the`
modified: `this gives the a lower bound on the`

The issue points to a specific file, wordle/simulations.py, and line 455. Open that file, locate the line with the spelling error 'boudn', and change it to 'bound'. Verify the change by checking the context of the line to ensure it makes sense, and consider running any existing tests for the simulations module to confirm nothing is broken.
