Although `babel` has a lot of test cases, we still need to add edge
cases that `babel` doesn't have.
This PR will allow us to add out test cases to
`/root/oxc/tasks/transform_conformance/tests`. The directory structure
is consistent with `babel`
For example
```shell
# cd /root/oxc/tasks/transform_conformance/tests
- babel-transform-plugin–optional-catch-binding
- test
- fixtures
- your tests # add test cases here
```
