Documentation Edits

Cleaned up some language and longer sentences, and removed or combined a few repetitive phrases. I removed the installation example with @Latest: I thought it could potentially throw someone off as it was listed first. I included a note that using the latest version is possible by using @Latest, with a warning that it may cause unexpected changes. If you want to keep it, I would recommend putting it second to be safe, but that's your call!

I also included edited versions of the further explanation for utility classes and component systems (thanks again for that).

Overall, I tried to keep the language at the same level of casual and keep the edits light.
