Conflict between AWS CLI and Sphinx dependencies causing doc build failure (docutils version mismatch)

[zpoint]

bug reproduce:

# activate conda
cd docs
pip install -r requirements-docs.txt
cd ..
pip install -e .[all]
cd docs
./build.sh

output:

    'meta': (nodes.meta, 'docutils.nodes.meta'),  # type: ignore[attr-defined]
AttributeError: module 'docutils.nodes' has no attribute 'meta'
make: *** [html] Error 1

Its because awscli>=1.27.10 requires docutils<0.17,>=0.10, while our doc build use sphinx==7.1.2 which requires docutils<0.21,>=0.18.1
pip install -e .[all] gets docutils==0.16 from awscli>=1.27.10
pip install -r requirements-docs.txt gets docutils==0.19 from sphinx==7.1.2
The doc build only works with docutils==0.19

30 seconds slower install from source

They are not publishing this to pypi, if we want to install it we should install from source
