docs: correct bundledDependencies -> bundleDependencies

[nlf]

arborist normalizes bundledDependencies to bundleDependencies, this change corrects the documentation to match that reality

closes #5167

seems strange to me; "bundled dependencies" is what they are, they're not "dependencies for a bundle"

[nlf]

if you consider the package that is bundling the dependencies to be a "bundle" then they are bundle dependencies.

the main reason for correcting docs here is that arborist has been normalizing it the other way for a very long time, which means a whole lot of the packuments in the registry have been changed to bundleDependencies. changing it back to bundledDependencies is certainly possible, but making docs match reality is always the lowest risk approach to these things

I agree this change makes the most sense, but I think arborist chose the wrong normalization.
