Add template tests for beforeInput(s) / afterInput(s) options

[36degrees]

What

Add template tests to ensure that the beforeInput and afterInput options behave as expected for:

• Character Count
• Checkboxes
• Date Input
• File Upload
• Input
• Radios
• Select
• Textarea

Why

These new options were introduced in #4567 but no corresponding tests were added. We should add examples and tests to ensure that they work as expected; so that port maintainers are more likely to match the behaviour and to avoid accidental regressions in the future.
