[Hold] Agentic table parsing

[Paul-Cornell]

Also: Added all missing API settings for all enrichment node types (not just table-to-HTML with agentic table parsing), and their corresponding available providers and models. (Looks like there were some recent API updates made that I didn't know about.)

Main doc updates here are:

• https://unstructured-53-doc-64-agentic-table-parsing.mintlify.app/api-reference/workflow/workflows#enrichment-node -> see the various "Allowed values..." sections, especially the one for the Table to HTML task: https://unstructured-53-doc-64-agentic-table-parsing.mintlify.app/api-reference/workflow/workflows#table-to-html-task
• https://unstructured-53-doc-64-agentic-table-parsing.mintlify.app/ui/enriching/table-to-html#generate-table-to-html-output
