Pure refactor conans->conan for Conan client version __version__

[czoido]

The CI is broken because this must also be changed:

conan/setup.py

Line 32 in 508ec9a

"conans", "__init__.py"))

conan/setup_server.py

Line 35 in 508ec9a

"conans", "__init__.py"))

I'll push the changes and update the release pipeline that will be affected by these changes too.
