Don't accept `-Version` if string array was supplied to `-Name` in `Install-PSResource` and `Save-PSResource`

Prerequisites

• Write a descriptive title.
• Make sure you are able to repro it on the latest released version
• Search the existing issues.

Steps to reproduce

With Microsoft.PowerShell.PSResourceGet v1.0.6 you can supply -Version when supplying multiple resources with -Name.

That does not make much sense and should error instead of event trying, in my opinion.

Example command:

Install-PSresource -Repository 'PSGallery' -TrustRepository -Scope 'CurrentUser' `
    -Name 'Az.Accounts', 'Microsoft.Graph.Authentication' -Version '3.0.5' -Verbose

Expected behavior

ERROR: -Version can only be supplied if -Name is a single value.

Actual behavior

PS > Install-PSresource -Repository 'PSGallery' -TrustRepository -Scope 'CurrentUser' -Name 'Az.Accounts', 'Microsoft.Graph.Authentication' -Version '3.0.5' -Verbose

Start by reproducing the commands shown for Install-PSResource and the equivalent Save-PSResource case, then trace their parameter validation. The change is done when supplying multiple -Name values with -Version produces the stated error, while a single -Name value continues to work; add or update coverage where the existing command tests are located.
