Documentation says python 3.6+, but tablib 3.7.0 dropped support for python 3.8

The "Pythons Supported" section of docs/intro.rst says "Python 3.6+ is officially supported."

This seems a bit out of date. Checking the release notes, it looks to me like:

• The last version to support Python 3.6 was tablib 3.1.0 (see Drop support for EOL Python 3.6 #513)
• The last version to support Python 3.7 was tablib 3.4.0 (see Drop support for EOL Python 3.7 #551)
• The last version to support Python 3.8 was tablib 3.6.1 (see Drop support for Python 3.8 #598)

I've integrated tablib into code bases that can't upgrade their Python version and it's a little confusing to have to figure out why the latest version of tablib doesn't work.

A quick fix would be to just update the language to say "Python 3.9+ is officially supported".

Or, if Python 3.6 is still considered officially supported since tablib 3.1.0 supports it, maybe add a couple lines documenting what versions of tablib one should use for older Pythons.

Thanks for the report.

Python 3.6 is no longer supported and that line is out of date.

I updated it to 3.9 in #607 but we're not going to merge that yet, so let's update it separately.

And on second thoughts, I suggest we remove that line altogether, as we've already forgotten to update it three times (other projects also tend to do the same), and it duplicates the definitive metadata in pyproject.toml.

+1 to remove that section.
