bug/With auto.partition table extraction not enabled in pdf

[Akashtyagi]

Describe the bug
Since the pdf_infer_table_structure is deprecated. Using the simple partition strategy should work, but it doesn't.

Instead skip_infer_table_types has pdf mentioned in it, hence it requires to explicitly pass "skip_infer_table_types=["jpg", "png", "heic"] with it.

Why do we have "pdf" present under skip_infer_table_types ?

To Reproduce
Provide a code snippet that reproduces the issue.

from unstructured.partition.auto import partition
elements = partition(filename="test/table.pdf", strategy='hi_res', chunking_strategy='by_title')
tables = [el for el in elements if el.category == "Table" and table.metadata.text_as_html]

Expected behavior
Ideally, just using auto.partition() should infer table structure for PDF too, as it does of other file types.
