pypdf package version conflict between llama-index, llama-index-readers-file, and graphrag-sdk

[priyansh4320]

Describe the Bug

• llama-index-readers-file 0.4.11 requires pypdf<6,>=5.1.0.
• graphrag-sdk 0.8.0 requires pypdf<5.0.0,>=4.2.0.

The latest graphrag-sdk 0.8.0 causes conflicts with llama-index and llama-index-readers-file due to a mismatch in the versions of pypdf.
