Dependabot-core: Update badges to be compatible with the new native GitHub Dependabot

[CasperWA]

The otherwise excellent badge (or shield) is currently "failing", writing inactive when moving to the new native GitHub Dependabot system.
This sends the wrong message, hence it should be updated to the new system as well.

@CasperWA thanks for reporting this! Adding to our backlog.

@feelepxyz do you have a timeframe for a fix?

I just started migrating repos over to the version of dependabot and ran into this too...

@feelepxyz maybe a good idea to prioritise this in the backlog? As you can see, many projects are dropping dependabot badge which is a great marketing for your work.
