🛠️ [TASK] : Add automatic retries

[jmgilman]

Feature Title

Add automatic retries

Feature Description

The run action should support automatically retrying earthly invocations when they fail. This helps alleviate things like flaky tests or random transient errors.

Use Case

A new input will be added to specify the number of retries to attempt before giving up on an invocation. The action will automatically retry N times before failing. Ideally, a random backoff should be implemented to decrease the chances of certain errors propagating (i.e., rate limits).

Is this a modification to an existing feature?

Yes
