Add "/build/" to the .gitignore

What the title says.
I assume most people who aren't using Visual Studio would use build instead of out.

This seems like something you should put in your .git/info/exclude rather than in the shared repository, since we don't mean anything special by a directory named "build". However, I don't see specific harm in doing this, we already exclude "out" for a similar reason, and we are unlikely to use that name "build" for anything else....

Essentially my entire line of thinking :P

Eh, OK.

I'm not sure how someone would end up with a /build/ directory (what process would they be following, and why isn't it in our documentation?) but I have no objection to this change.

As stated in this comment #572 (comment) using VS Code and the CMake Tools extension, that has build as the default build directory.

(Apparently I can't type on mobile without accidentally tapping on comment and close pull request).

Thanks for this small improvement! 😸
