Unify props of multiline / localized inputs

[dferber90]

Problem

At the moment we use a mix of props to basically explain the same two concerns, which adds unnecessary mental overhead when using our components.

The two properties we need to address

• Our multiline components can either have multiline text expanded by default or not
• Our localized components can either have all locales visible or not

At the moment we use the following props to express this:

Component	Property
MultilineTextInput	isDefaultClosed
LocalizedTextInput	isDefaultExpanded
LocalizedMultilineTextInput	isMultilineDefaultExpanded areLanguagesDefaultOpened

Note that isDefaultClosed and isMultilineDefaultExpanded address the same concern. However they're worded differently and they even have opposite default states.

Similarily, isDefaultExpanded and areLanguagesDefaultOpened address the same concern. Their wording is completely different as well and they have opposite defaults too.

Solution

We can boil the four different prop names down to just two different prop names; one for each concept.

Component	Property
MultilineTextInput	isMultilineDefaultExpanded
LocalizedTextInput	areLanguagesDefaultOpened
LocalizedMultilineTextInput	isMultilineDefaultExpanded areLanguagesDefaultOpened

I'm not too enthusiastic about these names and I'd welcome suggestions 👂
