Feat: Dependabot Config

[rblaine95]

Dependabot recently got support for Docker Image version bumps in kubernetes manifests.

nice !

I think it'll be a good idea to leave this PR open for a day or so.
I've cherry-picked this commit onto my master branch in my fork just to give dependabot a day to verify it works as expected.

I expect dependabot to open PRs on my side to update the actions (checkout@v2 -> checkout@v3) and bump the image version.
I hope dependabot also bumps the Chart version.

Looks like the Actions updates are working

[juanpicado]

Awesome 👏🏻!!

[rblaine95]

Ah, ok, after some digging I see why it's not updating the image tag.

It looks like Dependabot parses the values.yaml file looking for image.tag, which we're not setting.
We're setting the image tag with .Chart.appVersion unless .Values.image.tag is set. 🤔

Edit: Setting the image version in values.yaml triggers Dependabot - rblaine95#7
Unfortunately, Dependabot doesn't bump the Chart version

Seems related to this dependabot/dependabot-core#1744 ?

Left a question. Nice contribution @rblaine95!

[juanpicado]

@rblaine95 have you tried renovate instead https://docs.renovatebot.com/modules/manager/helm-values/ ?

[rblaine95]

@juanpicado haven't heard of renovate, will take a look 👍

In the meantime, I'll remove the Docker dependabot config
