Add make.bat for Windows documentation builds

[ShlokBagwe]

Adds a Windows compatible make.bat script to build Sphinx documentation locally.

libpysal previously provided only a Makefile, requiring Windows contributors to manually call sphinx-build. Now, running make.bat html enables easy local Sphinx doc builds.

Is there a reason this differs from the one generated by sphinx?

[ShlokBagwe]

Actually this is a simplified version that mirrors the existing Makefile behavior, but it does differ slightly from the default Sphinx generated template.
If you say, I will replace it with the standard make.bat generated by Sphinx to improve the robustness and keep things consistent. Just let me know and I will update it

I think that would be preferred. We don't want to maintain our own versions of these files.

Thanks!

This part also needs to be included in here

libpysal/docs/Makefile

Lines 17 to 20 in e6bdd53

	# Custom target to generate files
	generate-rst:
	@echo "Generating custom files..."
	@python ../scripts/w_g_comparison.py

Is there anyone with a Windows machine who could test this out?
