Problem Description

Currently,coder_app resources do not support displaying tooltips, preventing template authors from providing contextual information. Users often don't understand what an app does before clicking, resulting in confusion and support requests.

Desired Solution

Add atooltip field tocoder_app Terraform resources with Markdown rendering (bold, italic, links). Display the tooltip on hover over app buttons in the workspace dashboard.

Example Usage

resource "coder_app" "rdp-coder-desktop" {  agent_id     = coder_agent.main.id  slug         = "rdp-desktop"  display_name = "RDP with Coder Desktop"  url          = "coder://dev.coder.com/v0/open/ws/${data.coder_workspace.me.name}/agent/main/rdp?username=Administrator&password=coderRDP!"  icon         = "/icon/desktop.svg"  external     = true+ tooltip      = "You need to [Install Coder Desktop](https://coder.com/docs/user-guides/desktop#install-coder-desktop) to use this button." # markdown supported field}
