Describe the bug

rga --rga-adapters=zip --rga-accurate doesn't work for zip file on macOS.

To Reproduce

Attach example file:
new.zip

Run command:
RUST_LOG=debug rga --rga-adapters=zip --rga-accurate --rga-no-cache -l 2018
Output

rg: new.zip: preprocessor command failed: '"/opt/homebrew/bin/rga-preproc" "new.zip"':

I find that mimetype is correct on Linux.
