Fetch a flake from a flake reference, and return its output attributes and some metadata. For example:
```nix
(builtins.getFlake "nix/55bc52401966fbffa525c574c14f67b00bc4fb3a").packages.x86_64-linux.nix
```
Unless impure evaluation is allowed (`--impure`), the flake reference
must be "locked", e.g. contain a Git revision or content hash. An
example of an unlocked usage is:
```nix
(builtins.getFlake "github:edolstra/dwarffs").rev
```
)",
.fun = prim_getFlake,
.experimentalFeature = Xp::Flakes,
