Fix "mb_substr(): Passing null to parameter #1 ($string) of type string is deprecated"

[stayallive]

As per the title :) Together with #35 this fixes all deprecations raised by the usage of this dependency in Former too 🎉

It sounds like this repo is possibly no longer maintained so I forked it.
https://github.com/kylekatarnls/html-object

I switched to GitHub Actions up to PHP 8.3 and merged your compatibility fix.

I would be happy to review/merge other fixes and grant access to the repo to those who might want to contribute on a regular basis.

It can be installed with:

composer remove anahkiasen/html-object
composer require kylekatarnls/html-object

@kylekatarnls, this seems like a good solution, with Former though I'm a weary it might introduce some weirdness if another library requires the non-forked dependency. I tried to require both and did not get any errors but wouldn't that cause duplicated classes? I thought I saw some of that in the past but couldn't reproduce so wanted to check in case you had some insights 😄

Ah yes, I should add the "replace" key to ensure precedence.
