chore: fix gulp-utils dependency issue

With DefinitelyTyped/DefinitelyTyped#21004 the typings for @gulp-utils are declaring `chalk` as dependency of the types. This causes a conflict with the types from chalk and gulp fails everywhere in the CI. (DefinitelyTyped/DefinitelyTyped#21004)

As a temporary workaround we are locking the version of the gulp-util types to the working version `3.0.31`.
