Save summary on file

[davide-ventriglia]

Hi guyz,

So far I saw the DOCKER_BUILD_SUMMARY env to enable or disable the production of an output for the Github summary, but no option to save those output on a desired file/location.
I know that github save the summary of each step on a temp file on the runner system, but it's not very straightforward to try to retrieve that file.
So I was wondering if there is a way for the action to save the output summary on a file that could be eventually used somewhere else (with or without further manipulation).
Do you think it could be useful and/or doable in a future version of the action ?

thanksss for any feedback
