Remove or update unneeded dependecies (flask, community)

Is your feature request related to a problem? Please describe.
When installing newer packages I am running into errors with google colab more and more recently, because the packages preinstalled are outdated, e.g. installing newest version of click (as a dependency of a another package, namely (ldimbenchmark)) results in this error:

Attempting uninstall: click
    Found existing installation: click 7.1.2
    Uninstalling click-7.1.2:
      Successfully uninstalled click-7.1.2
ERROR: pip's dependency resolver does not currently take into account all the packages that are installed. This behaviour is the source of the following dependency conflicts.
flask 1.1.4 requires click<8.0,>=5.1, but you have click 8.1.3 which is incompatible.
Successfully installed big-o-0.10.2 click-8.1.3 docker-6.0.1 ldimbenchmark-0.1.17 pandas-1.5.2 requests-2.28.1 scikit-learn-1.2.0 tabulate-0.9.0 urllib3-1.26.13 websocket-client-1.4.2 wntr-0.5.0

Describe the solution you'd like

Update or remove it, as it seems no other package depends on it:

!pip install pipdeptree
!pipdeptree -r -p flask
!pipdeptree -r -p community
>>>
Looking in indexes: https://pypi.org/simple, https://us-python.pkg.dev/colab-wheels/public/simple/
Requirement already satisfied: pipdeptree in /usr/local/lib/python3.8/dist-packages (2.3.3)
Warning!!! Possibly conflicting dependencies found:
* Flask==1.1.4
 - click [required: >=5.1,<8.0, installed: 8.1.3]
------------------------------------------------------------------------
Flask==1.1.4
  - community==1.0.0b1 [requires: Flask]

Describe alternatives you've considered
Ignoring the error...
I now have to run:

!pip uninstall google-colab community flask -y  # Workaround for GoogleColab beeing out of date: https://github.com/googlecolab/colabtools/issues/3307
!pip install ipython ipykernel --upgrade        # https://github.com/googlecolab/colabtools/issues/2230
!pip install ldimbenchmark

Additional context
Other errors are coming by outdated ipython version but this is handled here: #2230

We're getting more up to date with these dependencies, for now you can always !pip install --upgrade
