Bump requests from 2.20.0 to 2.32.4

Python 2.7 was very sad with dependabot's change.  Fixed!

Also three docker improvements:

- Make development easier with docker by using the
  files from the current directory instead of checking out
  a fresh copy.  This clutters the top level directory a bit,
  but it feels like a good tradeoff.

- Have the docker app listen on port 8080 by default, as fiddling with port 80 is a bit scary

- Have the docker app accept commandline parameters

And, finally, a README.md improvement:

- Show an example script to tickle three vulnerabilities in vuln_apps

Fix overeager requests update incompatible with python 2.7
