Increase opcache limit

[stephdl]

See https://community.nethserver.org/t/nextcloud-the-php-opcache-module-is-not-properly-configured/19732

Nextcloud reclaims more memory and file keys storage

max_accelerated_files : 100 000 is the maximum value
opcache.memory_consumption : set to 256 I understand it must be < php_admin_value[memory_limit] = 512M
opcache.interned_strings_buffer: default is 8 increased to 32 (could be 64)

I couldn't find such warning on my server, nor I see a way to reproduce the issue.
Let's wait to see if it is an issue for many users and what is the real impact.

We are going to change the defaults only if it is really needed.

You are currently running PHP 7.3.29. Upgrade your PHP version to take advantage of performance and security updates provided by the PHP Group ↗ as soon as your distribution supports it.
Nextcloud 23 is the last release supporting PHP 7.3. Nextcloud 24 requires at least PHP 7.4.
The PHP OPcache module is not properly configured:
The maximum number of OPcache keys is nearly exceeded. To assure that all scripts can be hold in cache, it is recommended to apply opcache.max_accelerated_files to your PHP configuration with a value higher than 10000.
The OPcache buffer is nearly full. To assure that all scripts can be hold in cache, it is recommended to apply opcache.memory_consumption to your PHP configuration with a value higher than 256.
The OPcache interned strings buffer is nearly full. To assure that repeating strings can be effectively cached, it is recommended to apply opcache.interned_strings_buffer to your PHP configuration with a value higher than 8.

No real errors have been reported, so let's keep the original configuration for now.
