fix: use correct color scheme name AntergosNeXT instead of AntergosDark

- Look-and-feel defaults reference AntergosNeXT.colors (the file that
  actually exists in /usr/share/color-schemes/)
- kdeglobals in desktop-settings also fixed to match
- Fix plasmarc install path (no trailing slash) so file is named
  correctly
