Pin ansible-core in pre-commit ansible-lint hook

ansible-lint 6.22.2 (used by the pre-commit hook) is incompatible with
ansible-core >= 2.16 due to removed internal APIs it depends on.
Pin ansible-core==2.15.13 in the hook's additional_dependencies to match
test-requirements.txt, preventing cryptic import errors when running
pre-commit.
