Steps to reproduce the issue

I'm using Bearsampp, Win10 Pro, PHP8.2, Joomla 4.2.6. I wasn't aware that XDebug is activated in Bearsampp (and I don't know how to turn it off at the moment) ;-) So I needed a while to understand what is happening.
XDebug is throwing a deprected message

Deprecated: Using ${var} in strings is deprecated, use {$var} instead in libraries\vendor\voku\portable-utf8\src\voku\helper\UTF8.php on line 4653

which crashes front-end and back-end afterwards with error message

Failed to start the session because headers have already been sent by "libraries\vendor\voku\portable-utf8\src\voku\helper\UTF8.php" at line 4653.

Replacing all ${chars} with {$chars} in UTF8.php solved the issue. But it's a vendor library where Joomla or whatever is loading v5.4.51 where this PHP82 fix is not included: voku/portable-utf8#181 (v6.0.?).

wamania/php-stemmer#26 Looks like it's going to be tricky because this compat release is going to require a higher library version. @zero-24 we might need to put something in joomla-backports

Looks like @SharkyKZ already raised that with the maintainers, lets see how they react. Not happy to branch it out just for such a non reason but please let me know as soon as you notice that a decision is taken on that topic by them and I can create a repo on joomla-backports when we do need it.

FWIW, it already requires PHP 7.3 since 3.0. Although that's only because of a bump in phpunit dev dependency. There have been no code changes so it's still very much PHP 7.0 compatible.
