Update capitalize.js

In this way, it also works for uppercase texts and all the following words, not just the first one.

But what if I need to "capitalize" only the first word?

Definition of "Capitalization" is the writing of a word with its first letter in uppercase and the remaining letters in lowercase. A word and not a sentence.
Just look at how this is handled in CSS.
But if you want to improve the code so that it works with "paragraphs" and "names". You can add parameters.

Yeah, you right. I will try to do something about it.
