Thanks for your contribution. ❤️
I'll look at it more closely soon.
Have a nice weekend

I finally had some time to look into you PR and run some tests locally.
I found a few cases that behave differently from the existing methods:

faker.number.int({ 'min': 6, 'max': 9, 'multipleOf': 5 }) // Error: No suitable integer value between 6 and 9 found.
faker.number.bigInt({ 'min': 6, 'max': 9, 'multipleOf': 5 }) // 10

faker.number.int({ 'min': -9, 'max': 0, 'multipleOf': 5 }) // -5
faker.number.bigInt({ 'min': -9, 'max': 0, 'multipleOf': 5 }) // Error: Multiple of 5n should be less than or equal to max 0n.

Please fix these cases and add tests for them.
