Fix: Eurobert model was missing @strict decorator and invalid test kwargs (#44767)
* Fix: added missing attribute in docstring
* Fix EuroBertConfig missing @strict decorator and invalid test kwargs
EuroBertConfig was missing `@strict(accept_kwargs=True)` unlike its parent
LlamaConfig, causing failures when reloading saved configs that include
extra keys like `architectures`. Also fixed the test helper passing
BERT-style kwargs (`hidden_dropout_prob`, `type_vocab_size`, `is_decoder`)
that don't exist on the Llama-based config.
* fix
