Allow all integrations to toggle inherited setting via the REST API
### About
This issue is to expose the `use_inherited_settings` argument in all integration REST API endpoints.
In https://gitlab.com/gitlab-org/gitlab/-/merge_requests/154915 we are introducing a new `use_inherited_settings` argument to allow toggling whether an integration uses inherited, or custom settings.
In that MR the argument applied to ~"Integration::MicrosoftTeams" only.
### Proposal
We should support the `use_inherited_settings` argument for all integrations via the API.
We would update the integrations API docs with the new arguments.
