hashFiles() couldn't finish within 120 seconds.

(filing here since I understand that hashFile() is owned by https://github.com/actions/runner)

Hey!

We have migrated a semi-large Unity project from SVN to Git / Github and I am working on setting up Actions for a build pipeline.
Unfortunately, a step to create a cache for Unity-specific files is giving me a headache. If I understand the error message correctly, I am running into a 120 second timeout for that step.

As I see it, the timeout for hasFiles() is set here and there is no way to increase it, is that correct?
https://github.com/actions/runner/blob/100c99f2635be35c7ea690c58fa7d203725cac9e/src/Runner.Worker/Expressions/HashFilesFunction.cs#L16

Expected behavior
I imagine it makes a lot of sense that the job has a timeout. It would be helpful if it could be set from the step configuration for scenarios where a lot of files have to be hashed.

Start with src/Runner.Worker/Expressions/HashFilesFunction.cs at the referenced timeout line and trace how hashFiles() is evaluated for the workflow expression shown. Determine where step configuration could provide the timeout, then verify that a longer hash operation no longer fails at 120 seconds.
