[TASK] Disable PHP CS Fixer statement_indentation rule (#798)

Unfortunately, this has been broken for comments preceding a `case` within a
`switch` since PHP CS Fixer version 3.9.1.

See
- PHP-CS-Fixer/PHP-CS-Fixer#6572
- PHP-CS-Fixer/PHP-CS-Fixer#6490
- PHP-CS-Fixer/PHP-CS-Fixer#6490 (comment)
- PHP-CS-Fixer/PHP-CS-Fixer#7624

A configuration option `stick_comment_to_next_continuous_control_statement` was
added, but this has not yet been extended to cover `case` within a `switch`.

So, for the time being, we cannot use this rule if we want to comment `case`s
within a `swtich`.
