Add option to change timeout of 20ms of ICommandPredictor ("ICommandPredictor interface has a 20ms time out for responses from the Predictors")

Prerequisites

• Write a descriptive title.

Description of the new feature/enhancement

Currently:
"To ensure a responsive user experience, the ICommandPredictor interface has a 20ms time out for responses from the Predictors. Your predictor code must return results in less than 20ms to be displayed."
see
https://learn.microsoft.com/en-us/powershell/scripting/dev-cross-plat/create-cmdline-predictor?view=powershell-7.4

This seem to be source code, with hard coded timeout of 20ms, see "millisecondsTimeout: 20"

src/System.Management.Automation/engine/Subsystem/PredictionSubsystem/CommandPrediction.cs

The "problem"
I find this value too low, as some of the predictors are use take more time to calculate suggestions.
I wish this value could be configured by user (me), without need to compile PowerShell.

Proposed technical implementation details (optional)

Add option to change this value, eg by using some additional call for Set-PSReadLineOption or other.
Eg, currently the next lines are used to install a predictor.

Set-PSReadLineOption -PredictionSource HistoryAndPlugin
Import-Module .\bin\Debug\net6.0\SamplePredictor.dll

The following command can be added:
Set-PSReadLineOption -PredictionTimeout 30

Technically I'm not sure if this should be Set-PSReadLineOption, or in this repo at all,
because to install the predictor, "Set-PSReadLineOption" is used,
while the timeout code is in https://github.com/PowerShell/PowerShell/
