HYP-3527 Repair and add AssemblyScript examples in Modus documentation

[JairusSW]

FYI, formatting seems to mess up a whole lot of things especially for Go, so if you see any ugly formatting, it wasn't my intention for that to get pushed.

It's wanting to inline everything. For example,

type WeatherIntel struct {
  City        string  `json:"city"`
  Temperature float64 `json:"temperature"`
  Conditions  string  `json:"conditions"`
  Analysis    string  `json:"analysis"`
}

Formats to, well, this goop

type WeatherIntel struct { City string `json:"city"` Temperature float64
`json:"temperature"` Conditions string `json:"conditions"` Analysis string
`json:"analysis"` }
