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=stringdescription=<<EOT     # Select Workspace Image     See the [registry](https://container.registry.blah/namespace) for options.   EOTdefault="container.registry.blah/namespace/image:tag"}

Perhaps the description could be passed through a markdown processor? Longer term, it'd be nice to supportlist(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.
