Remove unneeded checks in Wix installer for WinRM prereqs or change link

Prerequisites

• Write a descriptive title.
• Make sure you are able to repro it on the latest released version
• Search the existing issues.
• Refer to the FAQ.
• Refer to Differences between Windows PowerShell 5.1 and PowerShell.

Steps to reproduce

There are two checks in the Wix for WinRM prerequisites.

https://github.com/PowerShell/PowerShell/blob/094e22e97ddcb982687f5e7a66c2567907e51124/assets/wix/Product.wxs#L177C59-L188

• The first checks for the Universal C Runtime.
• The second checks for the pwrshplugin.dll with MinVersion="6.3.9600.16383"

For both of these checks, the installer displays the message: "You can find download links here: https://aka.ms/pscore6-prereq"

1. Those prerequisites are automatically met for all versions of Windows that we currently support. So the checks are no longer needed.
2. This aka.ms link is outdated (PS6) and takes you to the Windows install article that no longer links to any of the downloads mentioned in the message.

Expected behavior

These messages should never appear, but the outdated code should be removed.

Actual behavior

Suggested changes

- Remove the unneeded checks and retire the aka.ms link

OR

- Change the aka.ms link to point to <https://www.microsoft.com/en-us/download/details.aspx?id=48234>, which is the download link for the Univeral C Runtime.

Start with assets/wix/Product.wxs around lines 177-188 and inspect the two WinRM prerequisite checks and their outdated aka.ms message. Remove the unnecessary checks or update the link as appropriate, then verify that the installer no longer displays those prerequisite messages.
