fix(arxiv): Use result.summary to fix AttributeError

The `arxiv` library has updated its API, and the `Result` object no longer has an `abstract` attribute. This commit updates the `fetch_arxiv_papers.py` script to use the `summary` attribute instead, which fixes the `AttributeError` that was causing the 'arXiv Daily Paper Crawler' workflow to fail.

Additionally, this commit updates the `update-starred-repos.yml` workflow to use a Personal Access Token (PAT) instead of the default `GITHUB_TOKEN`, as the default token does not have the required permissions to star repositories.
