🤖 AI PR Review Summary\n\nThis PR renames the installer script from mlcflow_linux.sh to mlcflow_unix_installer.sh and updates all references in the GitHub workflow and documentation accordingly. It also improves the installer script by conditionally adding the branch checkout argument only if specified, preventing potential errors. Additionally, the Action class in mlc/action.py is refactored to safely handle index entries with invalid metadata by skipping them and logging a warning, improving robustness. The version is bumped from 1.2.3 to 1.2.4. Risks are low but include potential breakage if any references to the old installer script name are missed. The design improvements enhance error handling and script flexibility.

🤖 AI PR Review Summary\n\nThis PR renames the installer script from mlcflow_linux.sh to mlcflow_unix_installer.sh and updates all references in the GitHub workflow and documentation accordingly. It also improves the installer script by making the branch checkout optional in the pull_repo function. Additionally, the Action class in mlc/action.py is refactored to handle invalid meta data gracefully by skipping such items, improving robustness. The README badges are updated to point to the dev branch, and the version is bumped from 1.2.3 to 1.2.4. Overall, the changes are low risk but require careful validation of the installer script URL updates and the new optional branch logic to avoid breaking installs or CI workflows.
