Code Review

This pull request bumps the version of the bootc-internal-blockdev crate from 0.1.0 to 0.2.0. A minor version bump like this usually indicates that new, backward-compatible functionality has been added, or in the case of a 0.x version, that there may be breaking changes. However, this pull request only contains the version bump itself, without any accompanying code changes. To maintain clarity and ensure that version numbers accurately reflect the code's evolution, version bumps should ideally be included in the same pull request as the code changes they correspond to.

This version bump from 0.1.0 to 0.2.0 suggests that there are new features or breaking changes. However, this pull request doesn't include any other code changes. It's a best practice to include version bumps in the same pull request as the code changes that justify them. This helps to keep the version history aligned with the feature history. If no functional changes have been made, a version bump may not be necessary.

LGTM though what I think we should do is change the minor/micro to match bootc ones always, should be scriptable.
