Optimize shellcheck ignores for actionlint pre-commit

Original failed run seen here:

https://github.com/apache/sedona/actions/runs/22992869182/job/66757741342

This hook is here:

https://github.com/apache/sedona/blob/3ac639748416b8e6975a409e53bb571bc36a6343/.pre-commit-config.yaml#L510

So maybe we can remove some ignores and clean up the code ??

Start with the failed workflow run and the actionlint hook in .pre-commit-config.yaml around line 510. Reproduce the pre-commit check, review which shellcheck ignores it reports, and determine which are still needed. Done means the unnecessary ignores and related cleanup are addressed without the hook failing.
