FAQ: Update Python version section regarding very recent versions.

The note relating to zulip#1145 is retained, but testing in CI indicates a more
specific error is given if there is no matching python for a user's
environment - now that versions 0.2.0 and 0.2.1 have been yanked from PyPI.

Instead of a broken install of a very old version, a recent pip should error
with a message along the lines of
`ERROR: Package 'zulip-term' requires a different Python: 3.11.3 not in <3.11,>=3.7'`
