Dev: Update documentation code examples to reflect new coding standards

[paulbalandan]

As we're all aware of the latest developments in our coding styles in a bid to shift to PSR-12 plus some of our custom styling, we've started rolling out code style changes in our code base. However, our new coding style tool cannot automatically correct also our documentation, which needs manual intervention.

We will be appreciative of a helping hand to assist us in updating also the code examples used in our documentation. Please submit pull requests while you can! 😎

@paulbalandan What are some of our custom styling?

It seems Coding Style Guide is not updated. Why don't you update it at first?

@paulbalandan I can write auto fix for examples in *.rst files but I don't know how skip non php examples.

[paulbalandan]

@WinterSilence thanks for the initiative! If you can tell me your general approach how you'll handle this maybe I can provide insights on skipping non php examples.

@paulbalandan

1. extract examples from *.rst files(lines with whitespaces at begin)
2. fix code style (phpcbf + codeigniter4/coding-standard)
3. replace examples
