Remove the warning message due to using the deprecated package

[git-hulk]

It will throw the warning message while running the Kong
due to using the deprecated packages pl.text:

[warn] the contents of module 'pl.text' has moved into 'pl.stringx'

Does it make sense to resolve this warning message by replacing
with the new package? If yes, I will happily submit a PR to do this.

Great! Please create a PR to fix it, thank you very much.

[git-hulk]

Thanks for your quick response, I will do it soon.

I'm sorry that this issue has already been resolved.
