[PATCH 2/2] t3600: amend test 46 to check for '.gitmodules' modification

[Shourya Shukla <periperidip@gmail.com>]

Following commit e5a439dc71 (rm: changes in the '.gitmodules' are
staged after using '--cached', 2021-02-18), amend test 46 of the script
to ensure that the test also checks for '.gitmodules' modification after
a 'git rm --cached <submodule>' i.e., the entry of the submodule in
question is removed from the file.
