Please document gulp.src() (vinyl-fs#src) followSymlinks option for gulp@4

[jmm]

In actuality gulp.src is require("vinyl-fs").src and there's documentation of some of its options duplicated / excluded, respectively. I mention it in case that can be the public API and it makes more sense to eliminate most of the duplication, link to the vinyl-fs docs, and just include notes that are relevant in the context of gulp if applicable. Like:

Note: Plugins might not implement support for streams.

But please document at least followSymlinks one way or the other.

Lots of stuff is missing from the 4.0 docs but that is already covered by #1281 and #1446 so I'm closing this.
