Hexo Updated to latest version

Updated hexo to the latest version, trying out a new post!

I went through updating hexo to the latest version, under the hopes some of the weird code highlighting issues would be fixed.

Example:

After the update:

It works!

I wanted to do this for a while, but was running into issues around my post_asset_folder images no longer resolving by just specifying cover.jpg (as an example). In the new world, I need to (for front matter only) specify the full path (minus root): /2021/11/20/my-post-title/cover.jpg.

Not sure what the cause of this change is, but I spent too long looking into it. Just had to go and update the front matter links to images for about 57 posts.

I did all of this because I had a few other posts in the (potential) works, and wanted to be in a better, more up to date state.
So yay!
