Describe the feature or improvement you're requesting

When adding a PowerShell file to the vector store it throws an error Files with extensions [.ps1] are not supported for retrieval.

A workaround could be to rename the ps1 files to .java or another supported format.

I would like to request PowerShell files be added to the support list.

Please let me know if I need to pursue this on a different channel. - Thank you
