fix: Ensure all tests use valid OpenQASM and upgrade to latest Braket SDK

[rmshaffer]

Issue #, if available:
Resolves #34

Description of changes:
Ensure that all tests generate valid OpenQASM, mostly by removing usage of the reserved keyword angle and duration as parameter names. This unblocks upgrading to the latest released version of the Braket SDK, so this PR does that as well.

Testing done:
All unit tests pass. tox -e notebooks passes.
