Add version logs to Latest-ADB-Installerbat

[mmanou]

• Add some logging to make the uninstallation of old versions more transparent to the user. This is because some more advanced users may have an old version installed in a different location. These new logs make it clear exactly which folder is being checked by the script.
• Add some end-of-script logging to make the user aware of the adb and fastboot versions currently installed on their system, and then provide an official Android link so they can compare this to the latest version.
• Fix some minor spelling and grammar mistakes.
