[Declension] Allow for declined pronoun selection from prepositions case annotations

Terms

Description

This issue is the second to add in the preposition case functionality to Scribe-Android.

• Note that this issue is blocked by #275, #267 and #270

When a user types a preposition, the next thing they'd like to see is what the possible pronouns that could follow might be. The functionality specifically is:

• The user types a preposition
• The user presses space
• The first autosuggestion key is replaced with an annotation in the style that will be developed in #135 and #275
• If there is more than one case that possibly follows a preposition, then all are shown on the annotation
• The user clicks on the button and is shown a declension view that uses the conjugation views developed in #267
  • The declension view that's shown is the first on the button in case multiple cases can follow the preposition

The view the user sees is similar to the following from Scribe-iOS:

• The user is then able to select a pronoun using the same functionality developed in #270

Happy to discuss this and review a PR once one's opened! 😊
