[QGIS-Developer] Missing html template files for Qgis server landing page

[David Marteau]

Hi,

If we install the Qgis server from the Qgis repositories: 
https://qgis.org/resources/installation-guide/?highlight=ubuntu#linux,
trying to access the landinpage '/catalog', then the request fail with 
the log error:

```Template not found error: 
/usr/share/qgis/resources/server/api/ogc/static/landingpage/index.html```

And, indeed,  no 'landingpage' directory exists at the above location.

The resources files existed in the 3.22 packaging, but are gone since 3.28

Is this a packaging error or do I missing something ?


Thanks

David Marteau
