smtk2ssrf windows installer not in downloads

[Salvador Cuñat]

Hi Dirk

I have just sent a PR updating the user-manual in the part related to
SmartTrak import, and noticed there are no windows installers for
smtk2ssrf in the downloads page.

Tnere are appimages, but no .exe files, which used to be there.

May be this has something to do with the issue reported by Matt and
Davide on 4.8 release about the link pointing erroneously to the
smtk2ssrf installer.

Best regards

Salva.
