[LTP] [PATCH v5 0/3] Update doc related Makefile

[Petr Vorel]

Changes from v4:
* Use sphinx version used on readthedocs.org (to really test in devel
  and github CI what will be deployed).
* Don't install sphinx in github CI (python3-sphinx package)
* Drop last 2 patches ("Makefile: Update 'doc' target, add 'doc-clean'"
  and "doc: Note 'make doc' in the building doc" => doc/Makefile should
  be rewritten to use generic_leaf_target.mk, then integration to the
  top level Makefile will not be a hack).

Tested:
https://app.readthedocs.org/projects/linux-test-project/builds/27705957/
