chore: migrate to main branch

[dandhlee]

Thank you for opening a Pull Request! Before submitting your PR, there are a few things you can do to make sure it goes smoothly:

• Make sure to open an issue as a bug/issue before writing your code! That way we can discuss the change, evaluate designs, and agree on the general idea
• Ensure the tests and linter pass
• Code coverage does not decrease (if any source code was changed)
• Appropriate docs were updated (if necessary)

Fixes #371 🦕

@parthea OwlBot seems to be failing on this PR, could you help take a look? Not sure what's triggering it to fail :/

@dandhlee Unrelated to your changes, there is a syntax error in owlbot.py here in the main branch.

Instead of

templated_files = common.py_library(
python.py_samples(skip_readmes=True)
    samples=False,  # set to True only if there are samples
    microgenerator=True,
    cov_level=98,

)

s.move(templated_files, excludes=[".coveragerc"])  # microgenerator has a good .coveragerc file

It should be

templated_files = common.py_library(
    samples=False,  # set to True only if there are samples
    microgenerator=True,
    cov_level=98,
)

s.move(templated_files, excludes=[".coveragerc"])  # microgenerator has a good .coveragerc file

python.py_samples(skip_readmes=True)

Fixed it. Please take a look again!
