mentat-controller.py not working with jinja2 version 3.0.1.
While upgrading mentat-alt from 2.8.108 to 2.8.109 there was an issue with re-starting mentat-controller. Modules mentat-storage and mentat-enricher were started just fine but mentat-inspector ended with an error: ValueError: The 'mentat' package was not installed in a way that PackageLoader understands.
As user#391 noticed, in 2d708954 the requirement for jinja2 was changed from 2.10.3 to 3.0.1. There seems to be an issue with jinja2 version 3.0.1.

Seems we'll need to make some changes before greenlighting Jinja 3. Mek, could you please take a look? I guess might affect #7041 (closed) too.

As it turns out the root of the problem was surprisingly somewhere else. The template files for inspection emails were not listed in the MANIFEST.in file, so they were not included in the wheel package at all. Since this feature was never used in production, the error was never discovered, because Jinja apparently previously did not report the problem with missing unused files for package_loader. I have upgraded Jinja to version 3.0.3 and all worked well on mentat-alt.
