Write the Windows installer in the language the rest of it is written in

install.sh and install-mac.sh are in English, and README.tr.md is where Turkish
lives. install.ps1 arrived in Turkish, and in a Turkish with the diacritics
stripped out of it, which is neither one language nor the other.

Two things while it was open: the `dikte` command ran whichever `python` the
PATH answered with rather than the one checked a few lines above it, and a
machine with no WindowsApps directory got no command and no word about why.
