[khinsider] Extractor unable to download sountracks

[vixellexiblade]

At the time of writing, running gallery-dl to download from Khinsider wouldn't print any output and exits successfully despite not making any new files nor folders.
I previously was enable to download this soundtrack around 30 Oct 2022. Now running with the verbose flag provides output.
This appears to apply to all soundtrack examples on the site, might be due to site change.

Sountrack previously downloaded on Windows through standalone executable in releases:

Looking at Issue #2611, I run the same command for comparison.
