'fiber-storage' outputs warning: Fiber#storage has borked keys and is being monkey-patched.

Abstraction

From fluent/fluentd#4488.

Looks like fiber-local uses fiber-storage from v1.1.0.
fiber-storage outputs the following warning message when require:

Fiber#storage has borked keys and is being monkey-patched.

fiber-local v1.0 does not output this warning because it does not use fiber-storage.

Fluentd uses console gem, and console v1.25 uses fiber-local v1.1.
So, this warning message occurs every time when executing Fluentd.

Is this a bug of fiber-storage or fiber-local?
Or is there something wrong with the usage?

(I can't find fiber-storage GitHub repository: https://github.com/socketry/fiber-storage, so I have made this issue here.)

Sorry, I missed this. I'll take a look. Maybe we don't need to emit such a warning.
