text: Title: Revert changes for local docs build once related sphinx issue is closed
  Body: In MR #2367, changes were made in `docs/Makefile`  to allow docs to be build locally using the `make html` command. This was needed due to errors that happened when attempting to built the docs with Featuretools installed in editable mode. Docs builds failing in editable mode *might* be related to an issue with sphinx.
  
  When sphinx issue 10943 (https://github.com/sphinx-doc/sphinx/issues/10943) has been closed and resolved, we should revert the changes that were mode to the Makefile as indicated by the comments here:
  
  ```
  .PHONY: html
  html:
  	# Remove the following line when sphinx issue (https://github.com/sphinx-doc/sphinx/issues/10943) is closed
  	python -m pip install .. --quiet --no-dependencies
  	$(SPHINXBUILD) -b html $(ALLSPHINXOPTS) $(BUILDDIR)/html $(SPHINXOPTS)
  	# Remove the following line when sphinx issue (https://github.com/sphinx-doc/sphinx/issues/10943) is closed
  	python -m pip install -e .. --quiet --no-dependencies
  	@echo
  	@echo "Build finished. The HTML pages are in $(BUILDDIR)/html."
