Fix dependabot errors

Updates the package dependencies to avoid dependabot errors.

I updated the `@types/gulp` to avoid some typings errors that were
introduced by incompatible versions of `@types/undertaker`.

Also, I forced resolution on `"glob-parent": "~6.0.0"` that avoids
a vulnerability on earlier versions.

I did a smoke test of features that use glob, as well as running a few
queries. All looks good.
