manual: Contributing -> Development, Hacking -> Building (#9014)
* manual: Contributing -> Development, Hacking -> Building

what's currently called "hacking" are really instructions for setting up
a development environment and compiling from source. we have
a contribution guide in the repo (which rightly focuses on GitHub
workflows), and the material in the manual is more about working
on the code itself.

since we'd otherwise have three headings that amount to "Building Nix",
this change also moves the "classic Nix" instructions to the top.

we may want to reorganise this in the future, and bring
contributor-oriented information closer to the code, but for now let's
stick to more accurate names to ease navigation.
