Fix similar code checking in codeclimate

[LiKang6688]

similar-code threshold describes the mass code block to be analyzed for duplication.
Refer https://github.com/codeclimate/codeclimate-duplication
for this settings.

Does this need to be under plugin? Does it work putting it under checks, as the other settings?

[LiKang6688]

Following the Configuring in https://github.com/codeclimate/codeclimate-duplication, it needs to be under plugin. We can use Code Climate CLI (https://github.com/codeclimate/codeclimate) to do analyze locally to see if it works as we want.

I just tried this rule on this branch #109. With the threshold at 3 it does not complain about styling-utils, which I think is a bit too weak. Those two functions could be replaced with one function taking one extra argument, which is something I think code climate should catch, but then you also get the false positives, like the propTypes.

Based on codeclimate/codeclimate-duplication#89

Would be really nice if this works, but I still see 6 fixed issues on codeclimate, there should only be the two propTypes that are fixed

[LiKang6688]

okay, look into it

[LiKang6688]

now it is correct

[haxxmaxx]

I don't know why, but if you look at codeclimate it is saying that the propTypes duplications are fixed, then there are two new issues that are exactly the same... We can try to merge this and see what it looks like when ir runs on main

sure
