Add clarification: PHP settings via `variables.php`

[chadwcarlson]

Where on docs.platform.sh should be changed?

• https://docs.platform.sh/languages/php.html#php-settings
• https://docs.upsun.com/languages/php.html#php-settings

What exactly should be updated?

Update the above pages so there is no confusion that PHP settings can be set using app_name.variables.php. One idea would be to replicate the table shown (and each value's defaults) using this syntax.

variables:
  php:
    'max_execution_time': 300
    'max_file_uploads': 20
    'max_input_time': 60
    'max_input_vars': 1000
    'memory_limit': '128M'
    'post_max_size': '64M'
    'zend.assertions': -1
    'opcache.memory_consumption': 64
    'opcache.validate_timestamps': 0

Thinking on it, it might make more sense to add a tab to the section here https://docs.platform.sh/languages/php.html#customize-php-settings

• third tab named Using variables.php
• Under that tab

variables:
  php:
    'max_execution_time': 300
    'max_file_uploads': 20
    'max_input_time': 60
    'max_input_vars': 1000
    'memory_limit': '128M'
    'post_max_size': '64M'
    'zend.assertions': -1
    'opcache.memory_consumption': 64
    'opcache.validate_timestamps': 0

Then reference that shown are the default values

This should be done now :) I'm just trying to figure out to preview my work in Upsun @chadwcarlson
