Rebase on curated-transformers 2.0.0

[shadeMe]

Description

This PR rebases the project on curated-transformers 1.0.0. This is a breaking change - spaCy pipelines trained with previous versions will not be compatible due to changes to parameter names, etc.

The piece encoder/tokenizer implementations remain untouched (except for a minor fix) for the time being since the serialization contract is currently undetermined on the curated-transformers side.

I'm worried that this may cause the same kinds of headaches as spacy-transformers v1.3.0. The only info we have in saved pipeline directories is which spacy version they were trained with, the versioning for spacy-transformers or spacy-curated-transformers is only included by spacy package.

[adrianeboyd]

It's nothing against this PR, just potentially a concern about publishing anything that uses earlier versions, such as the trf pipelines that have been published for spacy v3.7.0.dev0.
