(GH-11401) Clarify smart quotes behavior/guidance

Prior to this change, the `about_Quoting_Rules` topic document didn't indicate that PowerShell treats smart/typographic quotation marks as normal/programmer quotation marks, making them subject to the same escaping and quoting behaviors. This change: - Adds a note about smart quotation marks and guidance to avoid using them to enclose strings. - Adds an example of escaping smart quotation marks. - Fixes AB#309820 - Resolves #11401
