Clarify uses for results of `Get-PSReadLineOptions`

Start by locating the implementation and output formatting for Get-PSReadLineOption, then compare it with the formatting used by Get-PSReadLineKeyHandlers. Determine how color-specific keys should be distinguished from other options and confirm whether the proposed presentation preserves existing behavior; done means the output clearly explains which keys Set-PSReadLineOption -Colors accepts.

Prerequisites

• Write a descriptive title.

Description of the new feature/enhancement

When I was exploring some of the coloring options available in PSReadLine I was confused when the options I got from Get-PSReadLine were not working when I did Set-PSReadLineOption -Colors @{<KEY>='Green'} . The options were expressed like "Color" but in order for them to work you just need "". An example of this confusion can be seen in screenshot below:

Proposed technical implementation details (optional)

Have more clear formatting to show the color options verses the other options available in PSReadLine, perhaps a header showing these are color specific keys. Maybe utilize the same formatting that Get-PSReadLineKeyHandlers use.

Very rough design but just a thought for potential way to do this.

NOTE: this would be a breaking change so may not be worth however my personal preference is having more detailed and categorization of these options.
