`ViewState` object has incorrect types for some submission payloads

[zzullick]

Hello again! I found an issue with some of the types for view submission payloads.

The object in question is ElementValue which is used in ViewState.

Potential issues found

• Missing selected_date property
• Missing selected_time property
• selected_conversations property is string but should be an array of strings
• selected_channels property is string but should be an array of strings
• selected_users property is string but should be an array of strings

For reference, here is the same type from Slack Bolt TS to compare against.
