Additional context

This build was broken by replacing typer-slim with typer in #491060. Upstream spaCy depends on typer-slim, although it looks like there's an attempt to change that.

spaCy used to build because, even though the nix package declared typer (not typer-slim) as a dependency, the nix typer package was actually typer-slim with a few optional dependencies enabled so the package name matched.
