Update Documentation To State That Existing Exporter Instance Have To Be Uninstalled For Changes To Occur

[nbgibson]

Apologies if this is self evident to most, but I'm both very tired and very stupid.

In order to implement exporter changes to a Windows instance that has a running windows_exporter service running, the existing instance of the service must be uninstalled and the service creation command msiexec /i windows_exporter.msi [flags] must be run again to do a fresh install with the newly desired configuration.

It would be nice if each execution of the msi would overwrite any existing service and config, but that would take a fair bit of work and just adding a line in the docs on the matter would help account for this edge case.
