Add a code fix for adding missing seq before {…}

[edgarfgp]

Details

I propose we add a code fix for adding missing seq before {…}. This is related to a language suggestion [Deprecate { start..finish } and { start..step..finish }] (fsharp/fslang-suggestions#1033) implemented in dotnet/fsharp#17772 which is currently in preview

• Similar to the VS dotnet/fsharp@0795506

Before

let xs = { 1..10 }

let xs = { 1; 10 }

let xs = id { 1..10 }

let xs = id { 1; 10 }

let xs =
    id {
        1..10
    }

let xs =
    id {
        1; 10
    }

After

let xs = seq { 1..10 }

let xs = seq { 1; 10 }

let xs = id (seq { 1..10 })

let xs = id (seq { 1; 10 })

let xs =
    id (seq {
        1..10
    })

let xs =
    id (seq {
        1; 10
    })
