Based on the other sources reporting yesterday, it appears the “partial re-float” story was fake news (or prematurely optimistic) given by an Egyptian govt official.
Yes, I found this story, just written an hour ago:
“Suez Canal Suspends Traffic As Bid To Refloat Grounded Ship Hits Trouble”

I don’t think it was fake news, but as you say, and overly optimistic Egyptian trying to mitigate the damage.
Now they’re saying it could take weeks, and the price of stuff will be severely impacted.
