Xdebug on Devilbox (aggregated thread)

Currently the Xdebug questions are separated in too many different issues, which makes it difficult to track. Let's consolidate them in here:

## Status

The documentation lacks behind and can not be updated at the momemnt as I don't have all the bits and pieces together. Let's find some common ground, so we can get this out of the way once and for all.

**:warning: Note:** This requires `Devilbox v3.0.0-beta-0.3` or later

The currently suggested Xdebug `php.ini` configuration for PHP 7.2 and above is as follows:

**file:** `./cfg/php-ini-X.Y/devilbox-php.ini`
```dosini
[PHP]
; Defaults
xdebug.mode = debug
xdebug.remote_handler = dbgp
xdebug.start_with_request = yes

; How to connect
xdebug.client_port = 9003
xdebug.client_host = host.docker.internal
xdebug.discover_client_host = false

; Logging
xdebug.log = /var/log/php/xdebug.log
xdebug.log_level = 7

; IDE Configuration
xdebug.idekey = PHPSTORM
;xdebug.idekey = VSCODE
```

Adding these two might also help:
```dosini
; https://www.php.net/manual/en/info.configuration.php#ini.max-input-time
; https://www.php.net/manual/en/info.configuration.php#ini.max-execution-time
max_input_time = 0
max_execution_time = 0
```

**file:** `./cfg/php-fpm-X.Y/devilbox-fpm.conf` (copy `devilbox-fpm.conf-default`)
```dosini
...
[www]
; https://www.php.net/manual/en/install.fpm.configuration.php
request_terminate_timeout = 0
...
```

**Updates to the above config:**

* 2023-01-05: Changed `xdebug.client_port` from `9000` to `9003`
* 2023-01-05: Changed `xdebug.discover_client_host` from `0` to `false`
* 2023-01-06: Fixed typos in filename (thanks @Ernestopheles)

## Next Steps

We need confirmation for the following host operating system setups:

* Linux
* MacOS
* Windows (with WSL2)
* Windows (without WSL2)

And for the following IDE's

* PhpStorm
* VSCode
* Sublime

If Xdebug is working for you, please post the configuration in here as well as the OS and your IDE.
