$sort from querySyntax function in @feathersjs/typebox does not consider the extensions param, so can't sort on extensions

[eXigentCoder]

Steps to reproduce

(First please check that this issue is not already solved as described
here - if it is a general question or suggestion please start a Discussion)

• Tell us what broke. The more detailed the better.
  I tried to add a nested sort field to the extensions for query synatx and it wouldn't work, I dug into the source code and saw that extensions are not considered, I'm not sure if this is expected behaviour or not?
  

• If you can, please create a simple example that reproduces the issue and link to a gist, jrepo, etc. This makes it much easier for us to debug and issues that have a reproducible example will get higher priority.

I managed to solve it for my case by passing in an intersect type as the main argument:

Expected behavior

Tell us what should happen

Ideally, it would be great if the properties passed in as extensions could be used on the $sort as well as the $select

Actual behavior

These properties are currently ignored
Tell us what happens instead

System configuration

Tell us about the applicable parts of your setup.
