ci(go): trigger test-go.yml on .golangci.yml changes too

The lint config change in 70529de (v2 schema migration) didn't
re-run Go CI because .golangci.yml wasn't in test-go.yml's paths
filter — the lint config was on dev but Go CI was still pinned to
the previous failure. Adding it to both the push and pull_request
filters so future lint-only edits retrigger the workflow.

Side effect: this commit itself retriggers test-go.yml (the
workflow file changed), so Go CI gets the v2 lint config now.
