fix: remove globalProperties

`globalProperties` is not supported AFAIK and was removed from the original PR except in the `mergeGlobalProperties` utils.
With the various parameters correctly typed, the code was throwing a compilation error as TS can spot that `globalProperties` is not a key of `GlobalMountOptions`.
