Fix duplicate labels_include_any key on claude/windows (#41955)

## Changes

Removes the duplicate `labels_include_any` mapping key from the
`claude/windows` fleet-maintained app entry in
`fleets/workstations.yml`.

This duplicate key causes a YAML validation error ("duplicated mapping
key") because the same key appears twice on the same mapping. The fix
keeps the first occurrence (before `categories`) and removes the second.
