template: Make isort exclude submodules from API projects

API repositories can include external git submodules under
`submodules/`, and those submodules may not use isort or the
repository's import-ordering rules.

The isort migration workflow runs `isort .`, so without an explicit
exclusion it can descend into external submodules and fail or modify
code outside the generated project. Add `skip_glob = ["submodules/*"]`
to the API-only branch of the generated `[tool.isort]` configuration.

Regenerated the public and proprietary API golden fixtures.
