lixPackageSets.lix_2_91: drop

Lix 2.91 has been one of our historical LTS releases given that the Lix
2.92 series suffered from an unfortunate curl upstream bug and it took a
lot of time to fix it, in addition of other papercuts with SSH
connections.

Lix 2.91 is the last release not containing the asyncification work we
started.

Lix 2.92 latest minors sorted out these issues and possess bits of
asyncification, it's a much easier target for HEAD cherry-picks because
it also renamed the directory `src/nix` to `lix/`.

Plans are the following:

* Lix 2.92 is skipped.
* Lix 2.93 is the new stable.
* Lix 2.94 is the next stable.

Once NixOS 25.11 releases, Lix 2.92 will be dropped, therefore: it's
dropped from the HEAD as of now.

Lix 2.92 suffers from slight performance issues that are made up in Lix
2.93, your mileage may vary.
