chore: update preview and make some errors somewhat more insightful

[Emyrk]

Also fixed a bug where json marshaling functions returned some opaque "Something went wrong".

This primarily just updates the golang used for dynamic parameters to match main

I also had to gzip the wasm. The wasm got to a size >100MB, not allowed by Github. We should probably bring down this size, but gzip was an easy solve and it gets gzipped anyway by vercel. There was some magic decompression going in in localhost vs vercel. These changes were tested locally and on vercel.

Test an example that was fixed:

terraform {
  required_providers {
    coder = {
      source = "coder/coder"
    }
  }
}

locals {
  vscode_name = "VSCode"            #<--------------- Local value
  ides = [
    {
      name = local.vscode_name,     #<--------------- Nested local
      value = "vscode",
    },
  ]
}

data "coder_parameter" "ide_picker" {
  name = "ide_picker"
  type = "list(string)"
  form_type = "multi-select"
  dynamic "option" {
    for_each = local.ides
    content {
      name  = option.value.name
      value = option.value.value
    }
  }
}
