Centering in Markdown is broken and different from before rework

[jesseb34r]

To my understanding, before the migration to tailwind centered text was generated using the centered-markdown className applied here. This class no longer has an associated style loaded so the centering isn't happening.

I think people are also saying that all headings were centered previously. I do not know if we want this, markdown classically does not center headings by default.

The simple fix for this is probably to apply the text-align tailwind class instead of the deprecated centered-markdown. And then if users want their headings centered they can use the >>> syntax.

Definitely not true, headings have always been left-justified by default, just as any other text.

This seems like a pretty simple fix, but just in case it requires any non-trivial involvement with the Markdown parser code, I tried to document that part pretty extensively (and I'm always available for consult if something is unclear).

@jesseb34r Fixes for centering have been deployed, can you validate whether or not the centering is working again for you?
