Thanks to this repository, I learnt a lot about the combination of nginx and php-fpm. Here's something I think that could probably be improved when reading the configs.

What does this implement/fix? Explain your changes.

• Let Xdebug work without specific settings for different OSes
• Improve README
• Fix typo in a comment
• Add missing Makefile targets in .PHONY and reorder it
• Remove unused fpm config: pm.process_idle_timeout
• Use /bin/sh instead for shell commands in the Makefile

Does this close any currently open issues?

No.

Any relevant logs, error output, etc?

No.

Any other comments?

No.

Where has this been tested?

1. Ubuntu 20.04.4 LTS + Docker 20.10.14
2. macOS Big Sur 11.6.6 + Docker Desktop 4.8.2 (Docker 20.10.14)
