[python] Fixup python examples / build (#2509)

## Description

This fixes up and renables the python examples builds.

Main fixes
- Test shell script just straight up didn't do what it was intended to
do
- Replace analog imus (and half refactored sims) with OnboardIMU
- Fixes swerve velocities function signature
- "regenerates" the default robotpy test

## Meta

Merge checklist:
- [x] Pull Request title is [short, imperative
summary](https://cbea.ms/git-commit/) of proposed changes
- [x] The description documents the _what_ and _why_, including events
that led to this PR
- [ ] If this PR changes behavior or adds a feature, user documentation
is updated
- [ ] If this PR touches photon-serde, all messages have been
regenerated and hashes have not changed unexpectedly
- [ ] If this PR touches configuration, this is backwards compatible
with all settings going back to the previous seasons's last release
(seasons end after champs ends)
- [ ] If this PR touches pipeline settings or anything related to data
exchange, the frontend typing is updated
- [ ] If this PR addresses a bug, a regression test for it is added
- [ ] If this PR adds a dependency, the license has been checked for
compatibility and steps taken to follow it
