chore(docs): Add clarification for Pro Tip on Part 4 of tutorial

[BreGoNunez]

Description

It may have been just me, but when I was following this part of the tutorial. I copied and pasted the code and replaced what I already had in the Head of my blog page, since I was following it sequentially. I faced various errors since the GraphQL query didn't have the data for the metadata; only to realize this was already handled by the Seo components some steps ago. So I wanted to make a note to make it clear that this wasn't necessary since we had the Seo component already.

Also, the video tutorial (pretty good!) doesn't mention or show this tip so it took me longer to realize my mistake.

Hi, thanks for the PR! Currently I'm more inclined to close the PR as we have announcements with "Pro Tip" throughout the tutorial. They are always separate callouts independent from the flow so I'm interested to know why for this specific "Pro Tip" you thought it would be about the tutorial?

Hi @LekoArts! No problem! This is my first PR so thanks for giving some feedback on the fit for it.
It's just that the other "Pro Tips", although independent of the flow, can be replicated within the project just for testing purposes, but this one, when testing it, it threw the error I mentioned, since we were updating our src/pages/blog.js page, and it was at the bottom I thought the last step would be modifying the export Head on (Use a page query to pull the list of post filenames into your blog page) and this Tip was about doing so.

However I understand your take, the Tips do actually "live on their own"; it could have been just a "zoned out" moment for me.

Thanks for the input! I adjusted your changes to point out part 6 of the tutorial, hope that makes it clearer

Thank you for the time and feedback! The summary of the note made it much clearer!
Thanks peeps for the Framework. Keep the amazing work.
