Objects and Object Constructors: Clarify prototype inheritance and Object.setPrototypeOf() usage

[dekr1sh]

Because

This PR improves the clarity of prototype inheritance. It explains how Object.setPrototypeOf() is equivalent to setting __proto__ or [[Prototype]] and why directly assigning Player.prototype = Person.prototype is incorrect.

This PR

• Improved explanation of Object.setPrototypeOf() and how it relates to __proto__ / [[Prototype]].
• Clarified why Player.prototype = Person.prototype is incorrect and why Object.setPrototypeOf() should be used instead.

Issue

Closes #28633

A couple of accidental line breaks have been added?

Single line breaks don't render any differently and new paragraphs need to be separated by a single blank line (i.e. double line break). So the bits you've changed, anything that should be in the same paragraph should be on the same line of text, and anything that should be a separate paragraph should have a single blank line separating them, as opposed to just a line break.
