Github actions - build, dependabot

[planetf1]

• dependabot

no definition in ~/.github/dependabot.yml to check a) github actions (no actions yet) and b) code dependency versions

This means we will not get alerted to dependency updates (as we are for all our other repos)

We could continue to manage manually, or enable.

However note that since this repo is a series of independent builds, each pom.xml would need defining in the dependabot.yml

• build

We currently don't have any build process to validate code in this repository - again the build action would need to
perform multiple builds, for each project

We should probably fix up both of these
