Update to 1.78.2 (#6201)

* Update to 1.78.1

No changes needed in the patches other than moving some lines around and
updating the CSP hash as usual.

The flake had to be updated as it was using Node 16.16 and 16.17 is
required at minimum now.  Also python seems to install python2 which is
marked as deprecated so explicitly install python3.

* Update to 1.78.2

Patches applied without any conflicts.

* Update commit environment variable

This was causing the commit not to be set.  It broke display languages
since that has a hard dependency on the commit for directory names.
Possibly broke other things.
