release-windows: Use current ProductVersion (#2867)

The filename of the daily built installer still contains 2.0 e.g.:
cppcheck-2.0.182-x64-Setup.msi
- Read the ProductVersion from productInfo.wxi and use it in the
file name of the cppcheck setup file.
- Add possibility to manually trigger this GitHub action using
  workflow_dispatch:
- Fix indentation, yamllint error:
  10:5 error wrong indentation: expected 6 but found 4 (indentation)
