cli/config: remove redundant capturing of loop vars in tests (copyloopvar)

go1.22 and up now produce a unique variable in loops, tehrefore no longer
requiring to capture the variable manually;

    service/logs/parse_logs_test.go:50:3: The copy of the 'for' variable "tc" can be deleted (Go 1.22+) (copyloopvar)
            tc := tc
            ^
