Modify rule S1110: Migrate To LayC - redundant parentheses (#3281)
Provide consistent examples for CFamily, CSharp, and Java.

Make JS, PHP, Apex, Go, Kotlin, and Scala consistent.

Python has its own syntax so inline relevant bits.

Other languages are not updated: their description is considered good
enough and it would require a significant investment to not mess up the
syntax in their examples.

== Why is this an issue?
Parentheses can disambiguate the order of operations in complex expressions and make the code easier to understand.
[source,{lang}]
----
a = (b * c) + (d * e); // Compliant: the intent is clear.
----
Redundant parentheses are parenthesis that
do not change the behavior of the code, and
do not clarify the intent.
They can mislead and complexify the code.
They should be removed.
