Colors should not be red for opcache.enable_cli, opcache.jit, opcache.jit_buffer_size ?

[kenjis]

The PHP ini default for opcache.enable_cli is 0.
https://www.php.net/manual/en/opcache.configuration.php
Also, JIT is disabled by default, becuase opcache.jit_buffer_size is 0.
See https://php.watch/versions/8.4/opcache-jit-ini-default-changes

Since what to do with these settings depends on the situation,
I have not defined recommended values.

If enabling them improves performance, they should be enabled。
If they decrease performance, they should remain disabled.

If we set the recommended values, we need to prove that it improves performance in most use cases.
