🚀 Feature: Add suggestions to parameter-properties rule

[JoshuaKGoldberg]

Bug Report Checklist

• I have pulled the latest main branch of the repository.
• I have searched for related issues and found none that matched my issue.

Overview

Right now, the erasable-syntax-only/parameter-properties rule only reports a message on parameter properties. It doesn't provide any suggestions for how to fix them. Let's add one in to switch to traditional class properties.

Additional Info

As a part of this work, the docs/rules/parameter-properties.md docs file should be added to as well. Right now it just has a straightforward codeblock. A PR fixing this issue should:

• Put a sub-heading on top of the existing example enum: ## Invalid Code
• Add another code block under a ## Valid Code with what the rule would suggest
