The "This could take a while" notes incorrectly imply that nix builds most (all) packages from source

[Sciencentistguy]

The phrasing of the text of the "this could take a while" boxes is unclear to me, in that it seems to suggest that most of the time nix will build a package.

With the nix run and nix develop examples given it is overwhelmingly likely that the packages will be cache hits. (Unless the user is on a wacky architecture or has manually removed hydra as a cache, i guess)

@Sciencentistguy Yes, this is indeed something that we should make more clear because it undersells Nix to suggest otherwise. I'll rework the text a bit.

I also wonder if it being a warning is a bit much, and subsequent warnings after 2.nix-run.mdx seem redundant.
