feat(workrb): add curriculum encoder and benchmark tests (#19)

[AleksanderB-hub]

Description

• I contributed a curriculum skill encoder model for skill extraction tasks, following the work: https://ceur-ws.org/Vol-4046/ (paper 5)
• Followed the example commit from ConTeXTMatch example, tested on TECH and HOUSE against the paper reported scores.

Checklist

• [yes] Added new tests for new functionality
• [yes] Tested locally with example tasks with a caveat that I could not find example task that would match this problem (job posting sentence --> list of skills to select). I can add this to the test code if needed, just let me know!
• [yes] Code follows project style guidelines
• [yes] Documentation updated
• [yes] No new warnings introduced

Hey Aleksander, this is an awesome PR and contribution, great job!

Before I can merge it, you'll have to make sure that the tests are passing. If you will commit your changes locally and push them, they will now run remotely and you can check them in this repository. To do it faster, you can also run the tests you implemented locally on your computer, e.g. running pytest.

Currently in the tests there seems to be an error to find the model:

Repository Not Found for url: https://huggingface.co/Aleksandruz/skillmatch-mpnet-curriculum-retriever/resolve/main/adapter_config.json.
E               Please make sure you specified the correct `repo_id` and `repo_type`.
E               If you are trying to access a private or gated repo, make sure you are authenticated. For more details, see 

Let me know if you have any questions, happy to help (:

I think it might have been because the model was private on HuggingFace. I made it public now, so it should work. Let me know whether the tests are passing now.

Re-ran tests, tests passing! Great contribution, LGTM. Closes #19
