ci: fix toolstate not pushing data for Linux

A recent commit modified toolstate to only push updated data when the `TOOLSTATE_PUBLISH` environment variable is present. This worked fine on Windows but failed on Linux, since Linux jobs run inside Docker containers and the variable wasn't forwarded inside it.

This changes the Docker startup code to set the `TOOLSTATE_PUBLISH` enviornment variable inside the container if it's present outside.
