Clarify Visual C++ Redistributable finding and docs (#2508)

Update docs and analyzer output to make it clear that Exchange
specifically requires the Visual C++ 2012 and 2013 Redistributable,
and that these are not replaced by newer versions. When a version is
reported as outdated, the message now specifies which year's
Redistributable needs updating.

Fix double 'the' typo in documentation.

 **Description:**
 
-We check if the the latest Visual C++ Redistributable version, required for the installed Exchange server role, is installed or not.
+We check if the Visual C++ Redistributable versions required for the installed Exchange server role are installed and up to date. Exchange Server specifically requires the [Visual C++ 2012 (VC++ 11.0)](https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170#visual-studio-2012-vc-110-update-4-no-longer-supported) and [Visual C++ 2013 (VC++ 12.0)](https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170#visual-studio-2013-vc-120-no-longer-supported) Redistributable. These older versions are **not** replaced by newer Visual C++ Redistributable versions (e.g., the latest Visual C++ 2015-2022 Redistributable) and must remain installed.
+
+When Health Checker reports that a version is "outdated", it means the installed version of that specific year's Redistributable (2012 or 2013) needs to be updated to the latest release within that same series.
