Scan markdown files with alternative file extensions (.qmd, .markdown)

What happened?

When scanning markdown files for references, it is possible to select files ending with .markdown but it will throw an error

AUX/Markdown scan failed: Unsupported file type for <<redacted-path>>/file.markdown

Moreover, it is impossible to select files ending with .qmd in the file selection screen. Are there any plans to support quarto markdown or other markdown variants (e.g. .Rmd) when scanning for references?

Additionally (and I can open another issue for this if you'd like), I wonder if it would be possible to make scanning markdown for references scriptable, which would bring it closer to parity with scanning aux files (as per #1477). I tried to run the example in the docs but substituting the aux for a md file:

curl http://localhost:23119/better-bibtex/json-rpc -X POST -H "Content-Type: application/json" -H "Accept: application/json" --data-binary '{"jsonrpc": "2.0", "method": "collection.scanAUX", "params": ["/My Library/x", "<<redacted-path>>/file.md"] }'

but I get the following error in a zotero-styled popup window, which references the location of my pandoc binary:

pandoc parsing error Error: /opt/homebrew/bin/pandoc failed
