website: Try function documentation "provably" vs "probably" typo

This paragraph is trying to say that try only works for dynamic errors and
not for errors that are _not_ based on dynamic decision-making in
expressions.

I'm not sure if this typo was always here or if it was mistakenly "corrected"
at some point, but either way the word "probably" changes the meaning
of this sentence entirely, making it seem like Terraform is hedging
the likelihood of a problem rather than checking exactly for one.
