Revert "Initial work on formatting headers"

[ytmimi]

Reverts #5847

There are still some pending discussions about how formatting should be handled in the presence of headers #5847 (comment). @calebcartwright please let us know when t-style has made a determination on this 🙏🏼.

Perhaps we should make this version gated instead of just removing it, so we can keep developing it?

I'd considered this as well, but I'd rather not introduce churn. Instead of reverting if you'd be up for instead preserving the original header span contents (so as to not drop comments) and/or handle the non-pending case of block style comments that fit then I'd be okay with that too

please let us know when t-style has made a determination on this

for clarity, this isn't something t-style is going to specify. generally speaking dealing with these comment scenarios is something we're going to need to determine how to handle ourselves. it's just that I think we need to actually discuss and design how we want to do this as a first step

Go ahead with the revert. I will try to find time to restore it later with the functionality you described :)
