function.opcache-invalidate: Is "This function only invalidates in-memory cache and not file cache." still correct (or was it ever)?

Issue description

In manual page for opcache_invalidate() there's mentioned, that "This function only invalidates in-memory cache and not file cache.".
But as I tried to verify this (PHP 8.3.32 - to evaluate, if I can enable additional file_cache and what I would have to be careful about), I realized, that calling the function indeed removed the compiled file in the file_cache directory.
I even looked into the php-src code for opcache and in https://github.com/php/php-src/blame/master/ext/opcache/ZendAccelerator.c lines 1445-1448 (status today - commit c191020) a file cache invalidate is being called that deletes the file. This seems to have been implemented together with file_cache 11 years ago.

Steps to reproduce

1. Create two PHP files (e.g. optest.php and optest2.php - optest2 only defines a variable and optest accesses it)
2. include optest2.php in optest.php and open in browser
3. verify that binary for optest2.php is being created
4. call opcache_invalidate("optest2.php"); - e.g. in optest.php
5. open again
6. verify that binary for optest2.php was deleted

Suggested fix

Check actual behaviour and intended behaviour again and maybe remove sentence "This function only invalidates in-memory cache and not file cache." from manual page of this function.
