Cannot use `mockSteps` with specific `workflowFile` passed to Act

Hello there! First of all, thank you for this lib, it's turning out to be very useful so far so I appreciate the work put it into it!

Describe the bug I believe there's a bug if you try to use both step mocking and passing a specific workflow file to the act runner together

To Reproduce

Workflow file

```yaml name: Test on: [push] jobs: repro: name: bug repro runs-on: ubuntu-latest steps: - name: step 1 (mocked) run: echo "this is the real command" - name: step 2 (not mocked) run: echo "this is the real command" ```

Minimal test file

```javascript const path = require("path"); const { Act } = require("@kie/act-js"); const { MockGithub } = require("@kie/mock-github"); const { beforeEach, test, afterEach, expect} = require("@jest/globals"); let mockGithub; beforeEach(async () => { mockGithub = new MockGithub({ repo: { test: { files: [ { src: path.join(__dirname, "workflowfile-plus-mocksteps-repro.yaml"), dest: "/.github/workflows/workflow-file-plus-mocksteps-repro.yaml", } ] }, } }) await mockGithub.setup(); }) afterEach(async () => { await mockGithub.teardown(); }) test("workflow file + mockSteps repro", async () => { const act = new Act(mockGithub.repo.getPath("test"), ".github/workflows/workflow-file-plus-mocksteps-repro.yaml"); const result = await act.runEvent("push", { logFile: process.env.ACT_LOG ? "workflow.log" : undefined, mockSteps: { "repro": [{name: "step 1 (mocked)", mockWith: "echo this is the mocked command"}] } }) expect(result).toStrictEqual([ {name: "Main step 1 (mocked)", status: 0, output: "this is the mocked command"}, {name: "Main step 2 (not mocked)", status: 0, output: "this is the real command"} ]) }) ```

Expected behavior

Both options are able to be used in conjunction and the given workflow file executes with the proper step mocked

Logs Never makes it far enough for the act to actually execute, but the jest output is noted below.

Additional context I suspect this is a problem with the arguments passed to the StepMocker from the Act class. The StepMocker expects the workflowFile + cwd here but what actually gets passed from Act's handleStepMocking call is the path to the workflow file 2x so that when this function tries to find the workflow file, none of the if branches are a match.
