Fix typo in a page provider of DAM external template

The Default Nuxeo DAM Configuration external template (v10.10.2) in Studio has created the assets_search PP with the clause ecm:isTRashed = 0 (note the typo) which breaks the search. Where do things like this need to be reported & fixed?

The bug is not really a Studio bug per se, but I don't feel it's a NXP either
