Note whether azure-cli really needs an old version of Python

[nemobis]

The documentation currently states, on the python3 requirement:

The RPM package of the Azure CLI depends on the python3 package. On your system, this may be a Python version which predates the requirement of Python 3.6.x. If this affects you, find a replacement python3 package.

Following the instructions on Fedora 33, I'm prompted to install an old version of Python, 3.6:

I instead chose to ignore the python3.6 dependency and I got an older version of azure-cli instead, which states it's using Python 2.7. Is this intended?

$ sudo dnf install azure-cli -x python3.6

 Problema: package azure-cli-2.18.0-1.el7.x86_64 requires libpython3.6m.so.1.0()(64bit), but none of the providers can be installed
  - cannot install the best candidate for the job
  - package python3.6-3.6.12-2.fc33.x86_64 is filtered out by exclude filtering

This is not the same as #1815 because I could install python3.6, I just don't think it's wise to have it alongside or instead of my current python3.9.

[MonikaReddy-MSFT]

@nemobis -
Thanks for brining this to our attention. We will investigate it further and update you shortly.

[MonikaReddy-MSFT]

@nemobis - This as an engineering and not a docs issue. Hence I have raised an issue in Azure CLI Repo and the engineering team will look into this issue further.

At this moment, Since there is no doc update required, We will now proceed to close this thread. If there are further questions regarding this matter, please tag me in your reply. We will gladly continue the discussion and we will reopen the issue.
