ci(lint): exclude goconst linter from test files

Repeated string literals in table-driven tests are idiomatic Go
and do not need to be extracted into constants. This suppresses
385 goconst warnings that only appear in _test.go files.

Also set goconst ignore-tests so test-file occurrences are not
counted toward the threshold for production code strings, and
raise min-occurrences to 4 to avoid false positives on strings
like "TBD" that appear only a few times in production code.
