docs: expose documentation for randomizers

[ST-DDT]

Currently, we sometimes mention the generateMersenne32Randomizer and generateMersenne53Randomizer methods, but we don't have actual documentation for them on our website.

This PR adds both methods to the Utilities category.

Documentation:

• https://deploy-preview-3221.fakerjs.dev/api/utils.html#generatemersenne32randomizer
• https://deploy-preview-3221.fakerjs.dev/api/utils.html#generatemersenne53randomizer
