Allow fields to hide with the option to resume

Currently the input fields will persist until the user presses escape. Allow the fields to hide when other actions are performed, and prompt the user with a message to resume.

Working example in [Open Liberty Tools](https://github.com/OpenLiberty/open-liberty-tools-vscode/blob/97d1d2c192fe48f77aa08815d854ac42b8d9e99c/src/liberty/starterProject.ts#L170)

Start by comparing the linked Open Liberty Tools example in src/liberty/starterProject.ts with this extension's input-field handling and action flow. Trace where fields remain visible after actions, then verify that they hide appropriately and that a message lets the user resume the input process.
