Upgrade bundled php-parser to latest version

[ruudk]

Would it be possible to upgrade the bundled nikic/php-parser to the latest version?

• https://github.com/nikic/PHP-Parser/releases/tag/v5.7.0
• Print int custom raw value nikic/PHP-Parser#1127
• Remove custom printer pScalar_Int as no longer needed rector-src#7580 (comment)

We already ship. See build php-parser: https://github.com/rectorphp/rector/blob/main/vendor/nikic/php-parser/lib/PhpParser/PrettyPrinter/Standard.php#L179

What is the error you're getting when using these features?

Sorry, I was out of sync. This was not an issue after all! Thanks.
