Describe the bug

According to docs and typings it should be possible to use this plugin passing the config as an array of numbers:

* You can pass multiple type of values:
* - number[]: Enable the metric with custom buckets
* - ReturnType<typeof createHistogram>: Enable the metric with custom configuration

However, this doesn't work at all 😥

To Reproduce Steps to reproduce the behavior:

Expected behavior

That it works according to documentation, I should be able to pass an array of bucket sizes. I want to keep my bucket sizes consistent across all services in my stack.

Environment:
