Add global package informations for used python/npm/go recipes

[priv-kweihmann]

Note the currently used packages (and their versions) in these file. Use https://dependabot.com/docs/config-file/ to make them visible in github, so we can use the github notification service on update/security issues - this should work way better than release notfication (which get sometimes lost).

This could be easily created by a script, which uses "bitbake -s" as input

As the bitbake/oe universe is somehow different from all the other.
It should be enough to have a mail-watcher for all the repos used in this layer, as the following use cases exit (at least from my point of view)

• watch for new releases
• watch for commits to a certain branch
• watch fileserver

I experimented with the yocto distro_check script - this covered most of the topics and should be used for this purpose - so no need for something to be scripted here explicitly
