Allow wildcard in path for junit reporting

[cpernot-hf]

Feature Description

It would be great to be able to provide a wildcard as a path of "newrelic reporting junit" command. That would enable to send a bunch of files with one junit-reporter-action, see : https://github.com/newrelic/junit-reporter-action/

Describe Alternatives

Use https://github.com/bhovhannes/junit-report-merger in a previous step.
