💡 Tips for finding more occurrences

Run locally to see detailed breakdown:

./.github/scripts/count-earthly.sh

Note that the goal is not to reach 0.
There is anticipated to be at least some occurences of earthly in the source code due to backwards compatibility with config files and language constructs.

Code Review

This pull request adds the gomodguard linter to the .golangci.yaml configuration. Feedback indicates that this linter was removed in golangci-lint v1.60.0, and its inclusion will lead to fatal configuration errors in newer versions of the tool.
