feat(macro-prompts): preserve outer quotes

Previously if you had a macro prompt such as the following, the modal title would display `Question`, not `"Question"`. However, in other projects (Klipperscreen and Fluidd), they will preserve those outer quotes and they will be included in the title. This change makes Mainsail consistent with the other implementations.

```
RESPOND TYPE=command MSG="action:prompt_begin \"Question\""
RESPOND TYPE=command MSG="action:prompt_button Button1|RESPOND MSG=\"Clicked it!\""
RESPOND TYPE=command MSG="action:prompt_show"
```
