make install-for-dev is failing to install python modules

[Ahmad-Wahid]

I tried to install the plugin for development using make, and I had this below issue which is not able to install some dependencies.

pip-compile -o requirements/test.txt requirements/test.in
  ERROR: Cannot install -r requirements/test.in (line 8) because these package versions have conflicting dependencies.
Traceback (most recent call last):

    name, candidate = broken_state.mapping.popitem()
KeyError: 'dictionary is empty'

During handling of the above exception, another exception occurred:

Because of this issue, github actions are also failing.

Let's try make upgrade-deps first

[Ahmad-Wahid]

this would upgrade the dependencies but my concern is about install-for-dev.

[nhoening]

Which installs dependencies...

[Ahmad-Wahid]

yes.

[Ahmad-Wahid]

The issue is raising because of fakeredis latest version which is 2.17.0. If we downgrade it to 2.16.0 then we can close this issue. @nhoening
