[Feature Request] Ability to rename the context menu entry

Currently the context menu entry is hardcoded to "Open in Windows Terminal Preview" for the preview version.
This is very long string compared to everything else on the menu and therefore extends the width of the whole menu, so if possible please add an option to the settings to rename the context menu entry, or just change the default string to something smaller.

Start by locating the hardcoded Windows Terminal Preview context-menu label and the settings or context-menu entry point mentioned in the issue. Decide whether the shorter default text or a user-configurable name is the intended scope. Done means the entry no longer unnecessarily widens the menu and the resulting behavior is verified.
