Reset-WinGetSource removes the source, but does not add it back

Brief description of your issue

Reset should remove and "re-add" a source.

Steps to reproduce

PS C:\Users\denelon> Reset-WinGetSource -Name msstore
PS C:\Users\denelon> Get-WinGetSource

Name   Argument                               Type
----   --------                               ----
winget https://cdn.winget.microsoft.com/cache Microsoft.PreIndexed.Package

PS C:\Users\denelon> winget source reset
The following sources will be reset if the --force option is given:
Name   Argument                               Explicit
------------------------------------------------------
winget https://cdn.winget.microsoft.com/cache false
PS C:\Users\denelon> winget source reset --force
Resetting all sources...Done
PS C:\Users\denelon> winget source list
Name    Argument                                      Explicit
--------------------------------------------------------------
msstore https://storeedgefd.dsx.mp.microsoft.com/v9.0 false
winget  https://cdn.winget.microsoft.com/cache        false

Expected behavior

The source should have been retained.

Actual behavior

The source was removed.

Environment

Microsoft.WinGet.Client 1.8.1133

Start by reproducing the behavior with Reset-WinGetSource -Name msstore, then compare it with winget source reset --force and inspect the Reset-WinGetSource entry point. Done means resetting a named source removes and re-adds it, so Get-WinGetSource lists msstore afterward.
