Pin rocrate<0.15.0 until roc-validator supports RO-Crate Metadata Specification 1.2

rocrate 0.15.0 produces crates conforming to 1.2 spec by default, which
causes roc-validator validation errors like:

```
The RO-Crate metadata file descriptor MUST have a `conformsTo` property with the RO-Crate specification version
```

Also:
- Remove unused `BaseWorkflowPopulator.validate_invocation_crate_directory()` method.
