Add an option to ignore conclusion from this action

[TurpIF]

Hi,

There is scenario where one want to parse a JUnit report, but we do not want to mark the build as a failing one.
For instance, with automated retried tests, one could want to see all failing tests, but the test runner is the one indicating if tests are failing or not.

Another example is on this repository: JUnit reports are parsed for integration testing and demonstration. However, the build seems to fail on this repo while it is not.

What do you think about adding an option to skip the conclusion of the injected test reports ?
