👾 Description of the issue

This Github Action use the Hedera solo cli interally. You repo of solo can can be found here: https://github.com/hashgraph/solo

When creating this issue v0.31.0 is the latest release of solo: https://github.com/hashgraph/solo/releases/tag/v0.31.0 Currently the action uses solo v0.28.1. We need to update the solo version that is used in the action to the newest version. Sadly just changing the version number is not successfull since this will end in a broken GitHub Action. I assume that the CLI commands of solo has changed a little between v0.28.1 and v0.31.0. Documentation about the usage of solo can be found in the readme of the project.
