tests: update tests after latest 0.13.0 release

[reubenmiller]

Proposed changes

Updating tests to align with new 0.13.0 release which broken some tests which used the latest official released version.

• Replace usage of the now deprecated get-thin_edge_io.sh script in place of the newer thin-edge.io/install.sh script (hosted in https://github.com/thin-edge/thin-edge.io-website)
• Updated assertions which relied on the older clap cli formatting (e.g. USAGE: => Usage:)

Notes:

• There is still one test which relies on the older get-thin_edge_io.sh script as this script allows installing a specific version but the new version is not (but this is planned)

Types of changes

• Bugfix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Improvement (general improvements like code refactoring that doesn't explicitly fix a bug or add any new functionality)
• Documentation Update (if none of the other choices apply)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
