Remove `awscliv2.pkg` and `awscliv2.zip` from git repo history

[jeffi]

Describe the bug
Git clone requires a lot of time and disk space due to two binary files accidentally checked in a while back.

Proposed solution: force push.

To Reproduce
Steps to reproduce the behavior:

1. git clone
2. du -h

Expected behavior
Smaller disk usage.

Per Nikhil, requires fixing ALL branches.

git clone currently requires 87 MiB. Seems like the files are still in the repo history somewhere.
