feat(Containers.Result): add `ofOption` and `ofOptionWith` functions

```fsharp
let ofOption error option =
match option with
| Some x -> Ok x
| None -> Error error

let ofOptionWith errorThunk option =
match option with
| Some x -> Ok x
| None -> Error (errorThunk ())
```

Locate the Containers.Result module and inspect nearby conversion functions to determine where these additions belong. Implement the two functions shown in the issue, then build the project and confirm the new functions are available with the requested behavior for Some and None options.
