Fixing the HtmlString labels in latest versions of PHP

[nocodelab]

With this pull request the package is now compatible with the latest versions of PHP 8.*.
The HTML labels were not rendered due to non-compatible type declarations in label-related methods.
Enjoy!

Isn't this new typehinting syntax only supported in PHP 8.1? I would need to bump up the supported versions if so.

Ciao @dwightwatson, yes you are right.
Supported PHP version needs to be updated as well.

Ciao @dwightwatson, I have updated the composer.json with the PHP 8.1 version bump.
Can you please merge it?

Thanks!

Thanks for that. I'm still debating whether this is a change I want to make as it's quite dramatic.

I think we'd need 4 things in order to merge this:

• Drop support for Laravel 8.x - if it's going to target PHP 8.1 we may as well forward-focus this,
• Instead of HtmlString we should probably use the Htmlable interface instead,
• The Htmlable interface needs to be imported into the file (HtmlString is not, so it wouldn't work as-is), and
• It needs to test coverage for all affected methods to ensure they work with the new argument type.
