[FIX] Minimum Python version Odoo 12

[SirTakobi]

Minimum version should be 3.5:

Odoo requires Python 3.5 or later to run

(ref. https://www.odoo.com/documentation/12.0/administration/install.html#python)

I have tried to remove the setuptools constraint too, it might be no more needed

This will need to be coordinated with other changes in https://github.com/OCA/oca-addons-repo-template/blob/510592efb895bc586a22d1808d72b7125b645d86/src/.github/workflows/%7B%25%20if%20ci%20%3D%3D%20'GitHub'%20%25%7Dtest.yml%7B%25%20endif%20%25%7D.jinja#L19

The Chrome installation error might be related to https://support.google.com/chrome/thread/192592808

@sbidoul other than the Chrome error (should be temporary), any opinion about the Python version change?
I'm afraid it is a pretty big change, but maybe it was already discussed and 3.6 had been chosen for some reason I don't know

[sbidoul]

Ow I had not received notifications of this failing.

This can be fixed by running the job on ubuntu-20.04 instead of ubuntu-latest for python <3.8.

We have an example here: https://github.com/OCA/oca-addons-repo-template/blob/510592efb895bc586a22d1808d72b7125b645d86/.github/workflows/test.yml#L12-L36

Thanks, I have pinned the Ubuntu version but that does not appear to be the issue for chrome download

[sbidoul]

Sorry, I misled you. There is no need to change this.

[SirTakobi]

Dropped

[SirTakobi]

Just a note: the PR is in draft because I still have to fix the CI (as I wrote, I hope the signature error is only temporary).
I only pinged you for:

Well that risks making some branches red, and I'd say it is late to change that for such an old version.

TBH, python version compatibility with Odoo is a bit of a mess. It's very hard to get a reliable information about which python versions are really supported. So we look at which python version is used on Odoo runbot and odoo.sh and test with that in OCA.

What do you mean really supported?
The documentation might be wrong/not updated, but the truth is in the code too: Odoo 12.0, should be able to run at least in 3.5 because it is in https://github.com/odoo/odoo/blob/271b9468c999454527f106b4db177665afeef8ca/setup.py#L59.
