Add more suggestions for _.first

[mrmowji]

Currently, the suggestion we get for _.first might not be relevant in all cases. Array.prototype.slice() returns an array. But _.first from lodash returns a non-array value. So this line should be something like this I guess:

"alternative": "Array.prototype.slice() or arr[0]"

Also, I think we should add more aliases here. For example _.head should be prevented when _.first is prevented, because they're basically the same.

Also Array.prototype.at() or const [firstElement] = arr;
