Document Assigned Attributes of Pipeline Components (#9041)
* Add textcat docs * Add NER docs * Add Entity Linker docs * Add assigned fields docs for the tagger This also adds a preamble, since there wasn't one. * Add morphologizer docs * Add dependency parser docs * Update entityrecognizer docs This is a little weird because `Doc.ents` is the only thing assigned to, but it's actually a bidirectional property. * Add token fields for entityrecognizer * Fix section name * Add entity ruler docs * Add lemmatizer docs * Add sentencizer/recognizer docs * Update website/docs/api/entityrecognizer.md Co-authored-by: Adriane Boyd <adrianeboyd@gmail.com> * Update website/docs/api/entityruler.md Co-authored-by: Adriane Boyd <adrianeboyd@gmail.com> * Update website/docs/api/tagger.md Co-authored-by: Adriane Boyd <adrianeboyd@gmail.com> * Update website/docs/api/entityruler.md Co-authored-by: Adriane Boyd <adrianeboyd@gmail.com> * Update type for Doc.ents This was `Tuple[Span, ...]` everywhere but `Tuple[Span]` seems to be correct. * Run prettier * Apply suggestions from code review Co-authored-by: Sofie Van Landeghem <svlandeg@users.noreply.github.com> * Run prettier * Add transformers section This basically just moves and renames the "custom attributes" section from the bottom of the page to be consistent with "assigned attributes" on other pages. I looked at moving the paragraph just above the section into the section, but it includes the unrelated registry additions, so it seemed better to leave it unchanged. * Make table header consistent Co-authored-by: Adriane Boyd <adrianeboyd@gmail.com> Co-authored-by: Sofie Van Landeghem <svlandeg@users.noreply.github.com>
