Merge pull request #523 from cderici/dependabot-labels

#523

## Description

Adds custom labels for dependabot to use when opening chore PRs, as documented in https://docs.github.com/en/code-security/dependabot/dependabot-version-updates/configuration-options-for-the-dependabot.yml-file#labels .

Normally it adds the `dependencies` and `go` labels. The `hint/dependencies` and `area/go` are added. 

## Type of change

- Maintenance work (repository related, like Github actions, or revving the Go version, etc.)

## Additional notes

> [!WARNING]
> I'm not entirely sure if the new labels will replace the old ones or be added on top.
