New issue by numerys on void-packages repository

https://github.com/void-linux/void-packages/issues/42932

Description:
### Is this a new report?

Yes

### System Info

Void 6.1.20_1 x86_64 GenuineIntel uptodate rrrmFFFF

### Package(s) Affected

gscan2pdf-2.13.2_1

### Does a report exist for this bug with the project's home (upstream) and/or another distro?

_No response_

### Expected behaviour

I installed gscan2pdf along with tesseract.

    xbps-install -Su gscan2pdf tesseract-ocr-all pdftk

When gscan2pdf is ready to scan it should offer a menu to choose the Tesseract-OCR engine from. A correct menu would look like:

### Actual behaviour

The mentioned menuentry shows GOCR and only GOCR, beside it seems no GOCR package is in the Void [repository](https://voidlinux.org/packages/?arch=x86_64&q=gocr) and misses the Tesseract-entry. It looks like:

### Steps to reproduce

1. Run a desktop environment of your choice
2. Install gscan2pdf and tesseract
    `xbps-install -Su gscan2pdf tesseract-ocr-all pdftk`
3. Attach a supported scanner
4. Run gscan2pdf

A [gscan2pdf.log](https://github.com/void-linux/void-packages/files/11043819/gscan2pdf.log) is attached for documentation. It does show that the a tesseract-engine is found and a gocr-engine is not found.
