fix: file name formatting by xregexp

[Seunghyum]

Hello :) I still use your wonderful library. Thanks a lot.

This pr is from https://github.com/wswebcreation/multiple-cucumber-html-reporter/pull/148

I'm sorry about my inactivity.

Now I see your answer. thank you I made another solution to cover all language. xregexp package is little bit big (154.4 kb, gzipped 51.4kb). But it will be worth to take :)

If you want to make test case, I will make it in this pr. ;) Thanks to read my pr

Oh, I see your solution https://github.com/wswebcreation/multiple-cucumber-html-reporter/pull/148#discussion_r689451200

feature.id = `${ idPrefix }${ feature.id }`.split(" ").join("-").replace(/[^a-zA-Z0-9-_]/g, '-');

Your sugestion is also good. if you want to change your code, i will pr it :)
