[Refactor] Remove `examples/` folder

examples/README.md

-This folder is meant to contain instructions and task setups required to evaluate certain papers which may perform non-standard evaluation setups.
-
-Tasks can be supported already in the library under `lm_eval/tasks`, or if highly paper-specific, may remain as YAMLs in the respective `examples/paper-title` folder.
-
-## Verified Papers:
-
-* [WIP] [Chain-of-Thought Prompting Elicits Reasoning in Large Language Models](https://arxiv.org/abs/2201.11903)
-  * Further details can be found in the `chain_of_thought` subfolder.
-
-## Candidates to Support:
-
-* Least-to-Most Prompting
-* Algorithmic Prompting
-* Other in-scope prompting techniques
-  * Multi-turn prompting strategies are likely out of scope for the repository.
-* Pythia Suite: Term Frequencies over training
-* All setups from GPT-3 Paper
-* Varying few-shot orderings + selection ; Varying the label choices for multiple-choice tasks
-
-* Your Paper Here!
