Add schedule triggers to workflows whenever possible

This repository contains several GitHub Actions workflows, both hosted in this repository as reusable assets for use in
other projects, or to facilitate the development and maintenance of the `arduino/tooling-project-assets` repo itself.

The workflows are typically configured to run whenever any relevant file in the repository is changed. However, the
results of the workflow run are also dependent on the external environment it runs in, which include:

- The software running on the GitHub hosted GitHub Actions runner machines
- The GitHub Actions actions used by the workflow
- The dependencies that are installed by the workflow directly or via the GitHub Actions actions it uses

The workflows often do not fully pin to a specific version of given external tool. This was done in the interest on
reducing the maintenance burden of keeping the systems up to date. However, it also means that a new release can cause
the workflow runs to start failing (which might happen through an enhancement to that resource resolving a false
negative, or a defect causing a false negative).

When the repository file path trigger is used by itself, this sort of external breakage is only revealed when an
unrelated change triggers the workflow. That can be distracting even to a dedicated member of the project development
team, as well as confusing and discouraging to any contributor.

This type of change can be caught by adding a `schedule` event trigger that causes the workflow to run periodically in
addition to the other on-demand triggers. This allows the problem to be identified and resolved at the maintainer's
convenience, separate from the unrelated development work.
