Add Cursor IDE module with Terraform support

This commit introduces the Cursor IDE module, allowing users to add
a one-click button for launching Cursor IDE into their workspaces.
The module is designed to work with Terraform, making it
straightforward to manage and configure through infrastructure as code.

- Adds a comprehensive README for setting up the module.
- Includes example configurations for typical usage scenarios.
- Provides automated tests to ensure module reliability.
- Defines Terraform resources and variables to handle essential
  configurations like agent ID, folder locations, and order in the UI.

+# Cursor IDE
+
+Add a button to open any workspace with a single click in Cursor IDE.
+
+Uses the [Coder Remote VS Code Extension](https://github.com/coder/cursor-coder).

+```tf
+module "cursor" {
+  source   = "registry.coder.com/modules/cursor/coder"
+  version  = "1.0.15"
+  agent_id = coder_agent.example.id
+}
+```
+
+## Examples
+
+### Open in a specific directory
+
+```tf
+module "cursor" {
+  source   = "registry.coder.com/modules/cursor/coder"
+  version  = "1.0.15"
+  agent_id = coder_agent.example.id
+  folder   = "/home/coder/project"
