poetry.lock should be checked in to source control

poetry.lock should be checked in to source control

@aacebo My understanding is poetry.lock is similar to package.lock.json in nodejs. For sample projects, we can remove it from source control so users can always get latest packages that satisfies the dependency in pyproject.toml. The benefit to us is we don't need to maintain (update) the lock file to use latest packages to avoid security vulnerabilities. The JS samples in our repo also does not contain package.lock.json.

Please let me know how you think. I will add poetry.lock if that's what we want to do.
