fixed small number issue

[nobellium1997]

I just swapped the characters for numbers and put in a space so that it was easier to read.

Hi! Late thanks for the PR. I need to point out that due to the hacky natute of the code and normal numbers being not completely unusual as the first cahracter of a <title>, this change aggravates the known issue "will mess up with titles already starting with the characters ¹...⁸" mentioned in README.

this is the problematic code: whenever tab numbering changes, these lines attempt to remove the old number from the title.

tab-numbering/tab-numbering.js

Lines 13 to 15 in d4f3c27

	if (newTitle && numbers.includes(newTitle[0])) {
	newTitle = newTitle.substr(1)
	}
