feat: Update Unix install script

[dpaasman00]

Proposed Change

Updates linux install process to work with ocb and supervisor. Tested with debian, rhel, and ubuntu VMs.

Also updates docker images to work as well. For docker images, a config file needs to be volume mounted and a config argument passed. This is the command I used:

docker run -v ./local/docker-supervisor-config.yaml:/etc/otel/supervisor-config.yaml observiq/bindplane-agent-arm64:1.57.1-minimal --config /etc/otel/supervisor-config.yaml

Notably, the config file needs to have the agent executable path set as /collector/observiq-otel-collector
