Subject: [PATCH] community: add init for `UnstructuredHTMLLoader` to solve
 pathlib paths (#29091)

## Description
Add `__init__` for `UnstructuredHTMLLoader` to restrict the input type
to `str` or `Path`, and transfer the `self.file_path` to `str` just like
`UnstructuredXMLLoader` does.

## Issue
Fix #29090

## Dependencies
No changes.
