[BUG] Array input

[JokerGN]

When I send input of task as an array it will send command instead of value of it

for example I send input of workflow
{ hello: { world: [ "world" ] } }
so I want data in an array to be input for task
{ "hello": "${workflow.input.hello.world[0]}" }

but instead I get "world" we get "${workflow.input.hello.world[0]}" as input of task

At this time the input template only support /^\${[a-z0-9-_]{1,64}[a-z0-9-_.]+}$/i (${workflow.input.hello.world.0})

And I would be greate if it can support Javascript like notation e.g. a?.b[0].c
