Require pygments>=2.4.0...

Require pygments>=2.4.0 As noted in , running ipython with an old version of pygments leads to problems. Ipython sends ANSI color names to pygments to color output, but these names aren't in old versions of pygments. Before: with pygments 2.3.1 and ipython 8.0.0, opening an ipython instance and running In [1]: 1 / 0 # Expect ZeroDivisionError will crash ipython as `ansiyellow` is used to highlight the error. This PR requires pygments>=2.4.0, which is when pygments changed their ANSI color names.
