feat!: Rename model_name_or_path to model in ExtractiveReader (#6736)

* rename model parameter and internam model attribute in ExtractiveReader

* fix tests for ExtractiveReader

* fix e2e

* reno

* another fix

* review feedback

* Update releasenotes/notes/rename-model-param-reader-b8cbb0d638e3b8c2.yaml
