"python3 setup.py build_sphinx" gives an error

[jdkloe]

After switching to the renamed version eccodes (in stead of eccodes-python) for release 0.9.9 then
if I execute "python3 setup.py build_sphinx" after building the module I get the following error:

Running Sphinx v2.2.2

Configuration error:
There is a programmable error in your configuration file:

pkg_resources.DistributionNotFound: The 'eccodes-python' distribution was not found and is required by the application

The problem seems to be in file docs/conf.py which still refers to the project as eccodes-python in stead of plain eccodes on lines 35 and 43.
If I manually edit this file, and replace the 2 occurrences of eccodes-python with eccodes, then the documentation generation runs as expected.
