Spelling mistake in the build.zig.zon example file

[KellanHiggins]

In build.zig.zon, "ensure" is spelled "insure" in the example documentation.

I know not a big deal, but we aren't protecting it against theft or loss! :P.

Line 51.

I'm having trouble finding the location where this occurs. Can you give me a link to the page you're referring to?
