Set up FreeCAD presence on FOSS-Friendly (and other) video platforms

In furthering the reach of FreeCAD and making all assets and releases available on freedom/privacy-respecting FOSS platforms (and others), we're branching out to a list of platforms. This list will evolve over time, and should not be considered complete or mandated- We want to reach out to people where they are and that includes those who would rather not use YouTube, which is currently our only video posting platform.
