Typos fixed, QOL updates.

[WizardCell]

I spent the last two months reading through GASDocumentation and it was a fun journey. While I was reading, I made sure to notate any typos I found along the way. I barely could find any compared to how monolithic the doc is. Hopefully this PR has covered all the typos!

Some of the fixes I did was that I replaced some of the of "GD" prefixes (which stand for GASDocumentation) to "GS" (which stand for (GAS Shooter, i.e. the Sample Project). Maybe I shouldn't have done that, but if you look closely that caused me some confusion as in this case for example:

Before it used to say "UGD", and me as a reader was confused to see that the Sample Project uses some other totally different prefix. Let me know what you think regarding that? (I'm asking because in my PR I didn't replace all "GD" prefixes to "GS", which I noticed quite late).

For example, in this case:

I didn't replace UGD to UGS because this code doesn't exist at all in the GAS Shooter Sample Project.

Hello,

Thanks for looking into typos. The Sample Project generally refers to the Unreal project included in the GASDocumentation repository https://github.com/tranek/GASDocumentation/tree/master/Source/GASDocumentation. The prefixes for the code snippets should be correct. I understand why it's confusing since the snippets were pulled from many different projects - GD, GS, and even a few PA (my ParagonAssets project that's not public).

That makes total sense, thank you for clarifying things for me! I reverted the prefix changes I made, and committed a new PR.

Thank you for doing this! 🙌

Actually, thank you Dan for bearing with me through the process! 😄
