Determine changed files between base and current(head) commits.
The action accepts filter rules in the YAML format. Each filter rule is a list of glob expressions. The action will create corresponding output variables to indicate if there's a changed file match the glob expressions. You can use those variables in the if clause to run specific jobs/steps when specific files changed.
