docs: build the sphinx documentation on windows (#1891)

This commit enables building the sphinx documentation on windows.
The make.bat needed to do so was missing and is added in this commit.

To build the documentation from a fresh git clone you need to run these commands:

pixi install
pixi run update-flopy
pixi run get-exes
pixi run setup builddir
pixi run build builddir
pixi run benchmark
pixi run sphinx

Furthermore I added the rtd environment to the pixi.toml. When building sphinx you now don't have to manually pip install the requirements.rtd.txt. Instead the task will automatically use the rtd environment

Finally i updated the github pipeline files. The newly generated pixi.lock is using version 5 which needs a newer pixi version. I also removed the pixi run install as this is no longer required.
