Code card rendering should use api name from 'blockAliasFor='

Rendering of code cards uses the api name from the decompile info even when the attrs have blockAliasFor set. I'm thinking that if both the blocks and ```sig rendering use the alias name, the TS code cards should do the same?

The example here shows the api name with the _ while the alias name is set as onItemDropped.

//% blockId=events_onItemDropped
//% blockAliasFor="events.onItemDropped"
//% block="on $item dropped with $count"
//% draggableParameters="reporter"
//% group="Items"
//% weight=80 help=events/on-item-dropped
export function _onItemDropped(handler: (item: number, count: number) => void) {
    events.onItemDropped(handler);
}

Start by tracing the code card rendering path for TypeScript code cards, then compare how block rendering and sig rendering resolve blockAliasFor. Use the provided onItemDropped example to check the displayed API name. Done means the code card uses onItemDropped rather than _onItemDropped when the alias is set.
