Github Action

Inputs

Key	Example	Description
trust	https://github.com/maxandersen	Host pattern to add to be trusted before the script are executed.
jbangargs	--verbose	Arguments to pass to jbang before the script.
script	hello.java	File, URL or alias referring to script to run
scriptargs	--token ${GITHUB_TOKEN}	Arguments to pass to the script. Note: due to how github actions + docker arguments containing spaces gets treated as seperate arguments no matter how much quoting is done. If you need argument with spaces better to extend the docker file and call jbang directly.
