PHP 8.3 highlight_file/highlight_string output changes

[PhilETaylor]

Feature Request

Provide a migration rector for highlight_file/highlight_string for PHP 8.3 (and for UP_TO_PHP_83 LevelSetList etc)

PHP 8.3 makes several changes to how the highlighter process white-spaces, and now wraps the output with a <pre></pre> HTML tag. Further, it no longer converts new-line characters to HTML
tags, resulting in a multi-line highlighted HTML output.

Full details and diff examples at:
https://php.watch/versions/8.3/highlight_file-highlight_string-html-changes

This has already effected the Symfony project here (as an example, already fixed) symfony/symfony#51586
