chore: add Dependabot configuration file

[jiridanek]

https://issues.redhat.com/browse/RHOAIENG-5326

Description

A new dependabot.yml file has been added to the .github directory. This configuration file enables Dependabot to check for updates in our package ecosystems (i.e., github-actions and gomod) on a weekly schedule, focusing on security updates for the gomod ecosystem specifically.

Enabling this in repo settings

Then, in the rules, create rules for the manifests we want to keep up-to-date regarding security updates. Here are the two rules I created,

They are set-up like this

How Has This Been Tested?

https://github.com/jiridanek/kubeflow/pulls shows only two protobuf updates, which is a security update for notebook-controller

Merge criteria:

• The commits are squashed in a cohesive manner and have meaningful messages.
• Testing instructions have been added in the PR body (for PRs involving changes that are not immediately obvious).
• The developer has manually tested the changes and verified that the changes work

Hi @jiridanek. Thanks for your PR.

I'm waiting for a opendatahub-io member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.
