What is the change

Add "Related Section" referencing ESlint's magic number rule.

Purpose of Change

1. Expose more people to the awesome-ness of no magic numbers.
2. ESlint is constantly updating and maintaining their version of 'no magic numbers' linter rule that works with modern javascript & typescript. It seems like this repo hasn't been updated in a while.
3. Most people when they search 'no magic numbers' in javascript frequently land here. It would be nice for them to also know that it exists in ESlint as part of a core rule.

Questions

Are you ok with putting a notice in the beginning of the README, indicating to user's that it's worth checking out ESlint's version in the spirit of getting more people exposed to 'no magic numbers'?
