[examples] Fix Miniscript variants issue in compiler example

miniscript has extended the `Miniscript` struct to be generic
over a `ScriptContext`. This context is different for the `Sh`
variant (`Legacy`) than for the `Wsh` and `ShWsh` variants
(`Segwitv0`). Therefore, Rust is not happy with the single
`compiled` variable if it is used as an argument for all three
variants.
