MINIFICPP-2737 Add weekly CI workflow runs and status page

[lordgamez]

All Github Actions workflows are run weekly to avoid regression. The workflow run results are visible on the status page hosted on Github Pages.

Status page example can be checked at: https://lordgamez.github.io/nifi-minifi-cpp/status

Note: I think running workflow with both fips enabled and disabled can instantiate way too much jobs, so for automatic weekly runs running only fips enabled jobs should be sufficient.

I'd move this file elsewhere, as a CI status page is not really documentation. Maybe etc/status_page, or github_scripts/status_page, or a new directory called ci/status_page

I checked and the default for Github Pages for github project pages is the /docs directory and the convention seems to be that the websites for projects are located there and their subdirectories. I moved the index.html to /docs/status to align with this convention as the main index.html is usually reserved for the project documentation page. This way the status page will be found at https://apache.github.io/nifi-minifi-cpp/status Updated in a4f5b8a
