Update workflow status badges for GitHub Actions

Summary:
Workflow status badges for GitHub Actions have new URL format. Update them in our README because otherwise CI jobs incorrectly appear as failing.

The new URL format is:

```
https://github.com/OWNER/REPOSITORY/actions/workflows/WORKFLOW-FILE/badge.svg
```
e.g.

```
https://github.com/facebook/fbthrift/actions/workflows/getdeps_linux.yml/badge.svg
```

See https://docs.github.com/en/actions/monitoring-and-troubleshooting-workflows/adding-a-workflow-status-badge#using-the-workflow-file-name.
