Fix TypeError: _validateParameters is not a function

[Chessing234]

Bug: Parameter validation was throwing a hard error when triggered, because p5.prototype._validateParameters was incorrectly aliased to the undefined p5.validateParameters instead of p5._validateParameters.

Root cause: The alias in validate_params.js referenced an undefined property instead of the static method defined earlier in the file. This prevented the FES (Friendly Error System) from correctly logging parameter errors and instead crashed the program when it attempted to execute the wrapper.

Why fix is correct: Pointing the alias to the correct static method p5._validateParameters restores the intended FES behavior without crashing the program, fixing Issue #8818.
