ALAS-2021-1484 Changes

[rogerducky]

According to https://alas.aws.amazon.com/ALAS-2021-1484.html, a "severe" vulnerability was found in the python interpreters, requiring they be updated.

I couldn't figure out where the 3.8 versioned packages were, so was not able to update those.

Here's a diff for the Python 2.7 and 3.6 interpreters, though:
