No prompt for backfill, double `RESET EXPRESSION` when changing from computed to hard required link

[jackfischer]

• EdgeDB Version: 4.7 and 5.3
• EdgeDB CLI Version: 5.1.0
• OS Version: macos

Steps to Reproduce:

Make the following change from computed to hard link. CLI doesn't prompt for a backfill expression for the link like it would when introducing a normal required - of course migration then fails if you have any data.

module default {

    type A {}

    type B {
        someA: A;
        # required link a := assert_exists(.someA);
        required link a: A;
    }

}

$ edgedb migration create
did you alter link 'a' of object type 'default::B'? [y,n,l,c,b,s,q,?]
> l
The following DDL statements will be applied:
    ALTER TYPE default::B {
        ALTER LINK a {
            RESET EXPRESSION;
            RESET EXPRESSION;
            RESET CARDINALITY;
            SET TYPE default::A;
        };
    };
did you alter link 'a' of object type 'default::B'? [y,n,l,c,b,s,q,?]
> y

Little weird that it does RESET EXPRESSION; twice but that probably doesn't matter.

Hey, @quinchs. Does this need to be here in edgedb-cli, or does it need to transfer to edgedb?
