merge: Create firstRelativeMaxPointInArray.js (#772)

* Create first_relative_max_point_in_array.js

go over randomly generated array and print first spike or maximum point index in it
runs in O(log(n))

* rename file to match requested casing

* add comments

I prefer SOLID standards so that's why didn't add them at first but due to the repository requirements was needed to be added

* remove template unrelated comments

* Update equals check to match JavaScript standards

* create file skafolding and adjust filename to reflect main function

* using newer node version

* add tests

* add last line as empty line

* style changes

* move algorithm tests to test folder

* revert to old package lock file

* chore: add ending line feed
