Add documents about trailing comma is disabled when wrapping is enabled

[sanggggg]

Description

From Kotlin Slack

If wrapping rule is disabled then trailing comma on call site & trailing comma on declaration site is disabled, because w/o wrapping trailing commas can produce weird formattings. (see 10cb29c)

But there are no descriptions in rule documents about existence of this dependency and why exists. It may confuse users, so I added it.

Checklist

• PR description added
• tests are added
• KtLint has been applied on source code itself and violations are fixed
• documentation is updated
• CHANGELOG.md is updated

In case of adding a new rule:

• Rule is added to rules documentation

Tnx for improvement. I have improved it further. I first tried to explain it in review comments, but that turned out more difficult than actually changing it ;-)

I will push my changes and wait for your review of my changes.
