What did you do?

I am working on an esbuild plugin version of this library and noticed that the @opentelemetry/instrumentation-redis-4 package relies on the function name of classes. This can break when code is bundled due to bundlers renaming symbols.

It's worth noting that with esbuild there is a workaround, to use keepNames, but this a lot of diving into the instrumentation source code to discover the cause of the issue.

I know that feature is not merged, but based on the comments there seems to be demand for it, so relying on function names will be potentially problematic for any bundler-based instrumentations of this library.
