[Feat] Automatically suggest a translation key based on marked text / cursor

[Jeehut]

Problem Statement

Currently, the workflow enforces users to mark a text, press their preferred shortcut to open the Add Translation Window, and then type a key of their preference. Often times, especially in SwiftUI views, the semantic key is actually named very similar to the views the text is contained in, but the developer has to still think about a good semantic key and type it out.

Suggested Solution

RemafoX could suggest a key automatically and somehow allow the developer to simply 'review' it and confirm it without having to think about a new key or type anything. For example, when a SwiftUI view was named ActivitiesListView and the text was contained in a semantical SwiftUI view (property) like .navigationTitle("Activities"), the suggested key could be: "ActivitiesList.Navigation.Title", or for a Section when the text was within a footer: it could suggest "ActivitiesList.SomeSection.Footer".

Additional Considerations

This feature should go hand in hand with #22 and UX-wise it could be built into the auto-completion dropdown as an extra option before the user typed anything. Multiple options could be provided.

Additionally, also the "last used" key could be provided in the dropdown, maybe by removing the last component. E.g. if last ActivityForm.StateSection.Title was used, the autocomplete could provide ActivityForm.StateSection..

Note: This feature was first initially by @NickAtGit.
