[python-requirements.txt] Switch to chipwhisperer-minimal
So far, we haven't touched the chipwhisperer version but we will soon
have to update in order to re-enable FTDI MPSSE emulation and OpenOCD
debugging on the CW310. See lowRISC/OpenTitan#10625. However, this isn't
straightforward as more recent ChipWhisperer versions have dependencies
that require Python 3.7 or newer (e.g. numpy), whereas OpenTitan
requires Python 3.6 or newer.
ChipWhisperer has now prepared a minimal ChipWhisperer version that only
supports the CW310 but doesn't have these dependencies. As such
chipwhisperer-minimal will allows us to track more recent versions
ChipWhisperer while remaining on Python 3.6 for the moment (default for
Ubuntu 18.04). This commit switches to using chipwhisperer-minimal.

# Development version with OT-specific changes

-# Development version of ChipWhisperer toolchain
-# Use a development version until support for the CW310 board works in a
-# released version.
-# Prefer the archive download over a git clone to decrease installation time
-# (The chipwhisperer repository is rather large and uses additionally uses
-# submodules, which need to be fetched as well.)
