Fixed wrong character range in preg pattern in slugify function

[unti1x]

Fixed following warning:

Warning: preg_replace(): Compilation failed: invalid range in character class at offset 12 {"exception":"[object] (ErrorException(code: 0): Warning: preg_replace(): Compilation failed: invalid range in character class at offset 12 at vendor/danielstjules/stringy/src/Stringy.php:1174)"} []

I just came in to propose the same amendment.

Same.

Unfortunately this is blocking us from updating to php 7.3

We pushed an official fork of Stringy to Packagist with this fix because it was a pretty big deal for Statamic. Feel free to use it, we'll keep it supported as long as this repo stays a ghost town.
