Remove docs/Makefile, update root Makefile for docs build, and update.

[Sohaibameer204]

Removed the docs/Makefile to avoid confusion and streamline documentation builds.

Updated the root-level Makefile to handle documentation commands:

make html to build docs.

make cleandocs to clean the build and generated API files.

Updated the CONTRIBUTING.md file to reflect the new commands and remove references to the old docs/Makefile.

Thanks @Sohaibameer204! I had time to test this out and it all seems to work as intended. Though I don't think the docs/Makefile was deleted yet. I like the note about the previous Makefile - we'll keep that and remove it at some point in the future.

@drbenvincent i checked again the folder in which i was working and couldn't find the makefile which is inside the doc folder . Further what i need to do ?

Strange - I can still see the file on your branch. I pushed a commit which deleted the file.
