Instead of creating a new string, use TR.actionsSetDueDate from the backend.

This PR is irrelevant since these a tool string as are visible in dev build only, actual strings are coming from backend only

[david-allison]

This should come from the backend.

• update the xml files to note that this is the reason the strings are hardcoded
• update the code to set the title using (I believe): TR.actionsSetDueDate().toSentenceCase(this@SetDueDateDialog, R.string.sentence_set_due_date))
