Links to specific step logs and duplicate step names

**Describe the bug**
Links to specific step logs implemented in #170 finds step number by step name, but step name may duplicate. Looks like the step number should be retrieved from UI (globe icon of step with which index is clicked?).
https://github.com/github/vscode-github-actions/blob/bed6eac0cb7c76c1487f50402111e30d67c1354b/src/commands/openWorkflowStepLogs.ts#L13

**To Reproduce**
Steps to reproduce the behavior:
1. Clone https://github.com/muzimuzhi/hello-github-actions and open it with vscode
2. Find the 5th run of workflow "Test GitHub Actions itself"
3. Expand steps of its only job "Hello GitHub Actions", click the globe icon next to the second step named "Run dummy commands", also the 4th step
4. https://github.com/muzimuzhi/hello-github-actions/actions/runs/4902036880/jobs/8753647810#step:3:1 opened


**Expected behavior**
https://github.com/muzimuzhi/hello-github-actions/actions/runs/4902036880/jobs/8753647810#step:4:1 opened. Note it should be `#step:4:1`, not `#step:3:1`.

**Screenshots**
If applicable, add screenshots to help explain your problem.

**Extension Version**
`v0.25.7`

Start with src/commands/openWorkflowStepLogs.ts at the linked location and reproduce the duplicate-name case using the hello-github-actions repository and the fifth workflow run. Trace how the clicked step is identified, then verify that clicking the second “Run dummy commands” link opens #step:4:1 rather than #step:3:1.
