Improve on Checkstyle Guide

[chrisgzf]

Hello all,

I've received feedback from people that the guide to setup checkstyle that I wrote in #45 had a few flaws:

1. Language and phrasing could be improved
2. Was not portable, only works for Linux/macOS/WSL users
3. Graphics provided could be confusing because I used a customised shell prompt

There are a few improvements to be made:

1. Split up the guide into "Windows" and "macOS/Linux/WSL" sections, and write the section for Windows users
2. For the UNIX-like OS guide, retake the screenshots using vanilla bash
3. Perhaps split up the UNIX-like OS guide into 2 subsections
   a. "I just want to get checkstyle to work in this folder right now" subsection
   b. "Let's make a nice alias so that we can easily run checkstyle anywhere" subsection (we already have this now)
4. Improve on the phrasing of instructions

If anyone wants to give these a try, just leave a comment below stating what you want to take up (specific line items or the whole thing are both okay). If you have no idea how to start, no worries, I can guide you.

I intend to eventually work on the improvements over the next few weeks if nobody wants to take them up, but if anyone wants to give it a try, just leave a comment.

I can help make the modifications since I use Windows, WSL, and macOS. My Terminal is also not customised. I personally find the current version is great and contextual, though for the average joe, might seem too intimidating with all the teletypes LOL

Great! That'd be really helpful, because I don't really have access to Windows or WSL.

Was thinking of sectioning the current guide with panels like this. Though it's up to you how you wanna restructure the guide.
