* [cli] new 'author template' command
This new command allows users to extract templates for authoring
(customization) without the complexity of finding and downloading a
specific directory for their versioned artifact.
Example usage:
```
openapi-generator author template -g java --library webclient
```
This will write all templates with library-specific templates to the
'./out' directory relative to the current directory.
CLI will refer the user to
https://openapi-generator.tech/docs/templating after generation

* Fix path provider bug on CI
Previous path sorting logic failed on CI due to one or more files in the
cpp-qt5 script being associated with different path providers. This
caused a ClassCastException from Path#compareTo
This change uses Apache Commons PathFileComparator to sort by full path.
File list is copied to avoid sort side effects. Log on all exceptions.
