nightly: Temporarly delete commit message prompt from rules library (#45106)

Relevant for Nightly Users only, follow up to #45004.

In case you use nightly this will break preview/stable since
deserialisation will fail. Shipping this to Nightly so that staff does
not run into this issue. We can revert this PR in the following days.
I'll make a follow up PR which only stores the prompt in the database in
case you customise it.
