(webstorm) Strip .0 suffix from installation directory

When determining the installation directory for Webstorm, remove
any `.0` suffix that might be present in the version number.
Jetbrains doesn't use this part of the release version number when
installing, so this causes Chocolatey to create an empty
directory that never gets used or cleaned up.

Fixes issue chocolatey-community#2266 .
