2024 Aug updates to vm ubuntu 20.04 and ubuntu 24.04 (#628)

* Support negative-valued action parameters
by converting them in the Python helper code into a positive value
whose bit pattern is the 2's complement representation of the negative
value.

* Update README.md and user-dev-bootstrap.sh files to 2024-Aug-01
versions of open source P4 tool source code.
