fix(vscode): Allow script generation without connections and click in project root

[ccastrotrejo]

This pull request includes changes to the generateDeploymentScripts.ts file in the vs-code-designer app. The changes primarily focus on simplifying the code and improving the readability. The projectRoot parameter has been removed from the generateDeploymentScripts function, and it is now defined within the function itself. The connectionsData object is now created using a ternary operator to avoid unnecessary conditionals. The window import has been removed and replaced with vscode.window for better clarity.

• Removed the projectRoot parameter from the generateDeploymentScripts function and defined it within the function using vscode.Uri.file(projectPath).
• Simplified the creation of the connectionsData object using a ternary operator. Replaced window.showInformationMessage with vscode.window.showInformationMessage for better clarity.
• Replaced window.showErrorMessage with vscode.window.showErrorMessage for better clarity.
