Fix install casaos (#65)
* Add Docker API compatibility check for CasaOS Introduces a function to verify Docker API version compatibility with CasaOS. If Docker API version is 1.52 or higher, applies a systemd override to set DOCKER_MIN_API_VERSION for improved compatibility with older CasaOS versions. * Add containerd version check and fix for LXC/Proxmox Introduces detection for LXC/Proxmox environments and checks containerd.io version for compatibility with AppArmor. Downgrades containerd.io to 1.7.28-1 if a problematic version is detected, addressing potential 'permission denied' errors in containers. * Update installer version to V1.0.0 in run.sh Changed the displayed version in the welcome message from V0.4 to V1.0.0 to reflect the latest release of the BigBear CasaOS Installer.
