bench: refactor to use string interpolation in complex/float64/base/add

This commit refactors JavaScript benchmarks in
complex/float64/base/add to use string interpolation via
@stdlib/string/format instead of string concatenation when
specifying benchmark names. This improves readability,
facilitates easier debugging of malformed benchmark names, and
enables future linting of benchmark names.
