feat(exempt): add new options to exempt the milestones (#279)

* feat(exempt): add new options to exempt the milestones

closes #270

* test(milestones): add coverage

* test(issue): add coverage

* chore(rebase): fix all errors due to the rebase

also made some changes regarding the change I made with the lint scripts and prettier. I did not saw that some scripts were already here and I created to more to keep the old ones as well

* test(milestone): add coverage

* chore(index): update index

* fix(checks): remove checks over optional number options

the code was actually handling the case where the values are NaN so it's fine
