[FIX] Windows: Download Osmosis into in Osmosis and not into subfol…

…der, example `Osmosis/osmosis-0.49.2` (#261)

* [FIX] Windows: when unzipping Osmosis download, don't unzip version dir

- do directly unzip into Osmosis directory and not in a subdirectory named like the Osmosis version, i.e. 'osmosis-0.49.2'

* delete tooling_win files due to not working Osmosis v0.49.2 on Windows

* delete folders as well as files

* adjust comments
