### What problem does this PR solve?
Changed test priority markers from p1/p2 to p3 in three test files:
- test_table_parser_dataset_chat.py: Adjusted priority for table parser
dataset chat test
- test_delete_chunks.py: Updated priority for chunk deletion test with
invalid IDs
- test_retrieval_chunks.py: Modified priority for chunks retrieval
pagination test
These changes demote the priority of specific test cases to p3,
indicating they are lower priority tests that can run later in the test
suite execution.
