Thank you very much, @jackyhui96 !!
Two minimal adjustments and it will be ready to be merged :)

Will work on the changes now and push up, @elbrujohalcon could you label it with "hacktoberfest-accepted" so it counts towards my hacktoberfest PRs? :) Was meant to add this to your original issue which has the label but not sure on the correct process to do that

[elbrujohalcon]

I updated the repo tags (It had hacktober instead of hacktoberfest 🤦🏻 ).
I left a few suggestions to improve the code, too.
Besides them, now that we no longer support american/british as spelling types, I would be tempted to rename spelling_type as proper_spelling, or just spelling. What do you think?

This is great, @jackyhui96! Thank you very much!
The only missing things are to add the new rule to the list of default rules for erl_files and beam_files rulesets and to update the wiki.
