It'd be really nice, to enhance the workspace creation UI, to be able to use markdown in template parameter descriptions. This way, things like hyperlinks, headers, or anything else markdown, would be rendered nicely in the UI. Right now, it's straight text.

For example, a parameter in terraform could be enhanced like so:

variable "image" {
   type = string
   description = <<EOT
     # Select Workspace Image
     See the [registry](https://container.registry.blah/namespace) for options.
   EOT
   default = "container.registry.blah/namespace/image:tag"
}

Perhaps the description could be passed through a markdown processor? Longer term, it'd be nice to support list(string) variable types like is supported in coder v1, but that can be handled in a separate issue.

Here's the react code for parameter input.
