Added n98-magerun2 command to CLI containers

[MagicLegend]

Description

This PR adds the N98-Magerun2 binary to the CLI containers to be used during development. Magerun can be ran in a similar fashion as the other commands.

Fixed Issues (if relevant)

1. Resolves magento/magento-cloud-docker#345

Manual testing scenarios

E.g. in the images/php/7.4-cli folder:

1. docker build --tag magento/magento-cloud-docker-php:7.4-cli-1.3.2-magerun .
2. docker run --rm magento/magento-cloud-docker-php:7.4-cli-1.3.2-magerun magerun2 list

It should output the list of possible commands. I have noticed that for me it was required to force ANSI output with the --ansi flag; is this only on my machine, or reproducible across the board? If the latter we should consider updating the magerun2 command to always pass the --ansi flag.

I have tested the 7.2-cli, 7.3-cli and 7.4-cli containers. I might have missed some incompatibility somewhere.

Potential issues I've found during usage:

magerun is an alias for docker-compose run --rm deploy magerun2

Here I had left query logging enabled:

magerun sys:cron:list
Creating <project>-docker_deploy_run ... done

In Write.php line 62:
                                                     
  The path "/app/var/debug/db.log" is not writable.

ERROR: 1

Disabling query logging fixed the issue.

This appeared to happen after a cache flush and before a setup:di:compile:

Manually running setup:di:compile fixed the issue.

Due to the container executing magerun as www-data it cannot write log files:

Xdebug: [Log Files] File '/app/var/log/xdebug-deploy.log' could not be opened

Can we do something about the permissions this user has on the var/log directory?
