feat(jetbrains-gateway): add slug variable

[matifali]

• Update with new slug variable to allow using the module multiple times. Resolves jetbrains-gateway: allow specifying slug for multiple use of the module #321

LGTM

Nit: the reordering should probably have been done in a separate PR (but thank you for doing it!) since it isn't related to this change, and complicated the review.

@dannykopping Thank you. I will extract the ordering changes to a separate PR.

@matifali I just saw this on your v1.0.21 release.
Just wondering if it might have been better to have the default be the selected IDE? That way it should always be unique by default, I don't see a reason to add the same IDE more than once.

@djarbz The dault should already be the selected IDE> IF you use the module like

module "jetbrains_gateway" {
  source         = "registry.coder.com/modules/jetbrains-gateway/coder"
  version        = ">= 1.0.0"
  agent_id       = coder_agent.dev.id
  agent_name     = "dev"
  folder         = local.repo_dir
  jetbrains_ides = ["GO", "WS"]
  default        = "GO"
  latest         = true
}

Then GoLand will be the selected IDE when creating the workspace.

I did this for a user request to display two buttons on the workspace page, and an easier way to achieve that was to allow the module to be re-used. Unfortunately, that solution did not work because the same coder_parameter name can't be used twice.

Ahh, I was referring to this default.

variable "slug" { 
   type        = string 
   description = "The slug for the coder_app. Allows resuing the module with the same template." 
   default     = "gateway" 
 }
