Exception report

Since upgrading to version 2.3.3 on some of our Windows Servers under PS 5.1, the InlinePredictionColor appears as bright white making it look like a fully/already typed command - this is confusing because there's no visual way to tell if the command has been accepted (tab completed) or not without checking the cursor position. The exact value for this property returned by Get-PSReadLineOption is "$([char]0x1b)[97;2;3m". Under 2.2.6 it is "$([char]0x1b)[38;5;238m" (a grey).

I can see from the release notes:

### [2.3.0-beta0] - 2023-03-07
- Change default color for inline prediction to `dim` (#3493)

I'm not sure what this means exactly, but it also seems to conflict with the change?

Hi @robinmalik thanks for pointing this out! Turns out that conhost on Windows 10 does not support the dimming and italic font effect and makes it only white. I suggest trying to use Windows PowerShell in latest Windows terminal version and it should be fixed.

[StevenBucher98]

Apologies forgot Windows Terminal is not installed by default on Windows Server, you can change the prediction color back to old color with this command:

Set-PSReadLineOption -Colors @{ InlinePrediction = "$([char]0x1b)[38;5;238m" }

I suggest putting this command your profile or just disabling predictions by running Set-PSReadLineOption -PredictionSource None

Appreciate the one liner fix - a LOT of people using Powershell 7 in Windows Terminal these days though.

@StevenBucher98 Thanks Steven. I'll await the fix to resolve this (I wish Terminal was available for Windows Server!).
