Combobox Required has no bearing on Validity

[danielgarner365]

Description

When I have a ComboBox with required set inside a Form, I expect the following:

• The form not be submitted until there is a value set.
• A message appearing on the screen saying something like "Please select a value".

Steps to reproduce

1. Go to Code Sandbox Twilio Paste Template with Form and Combobox
2. Inside the form, click Submit.
3. See the message on the Input component - "Please fill in this field" - thereby indicating that the required property is working.
4. Enter a value in the Input component.
5. Do not select an item in the Combobox component.
6. Click submit again.
7. Note that we did not get a message regarding there being no value set on the Combobox and if we look in the console, we can see that the form has indeed been submitted.

I found related discussions that might be helpful:

• https://github.com/twilio-labs/paste/discussions/3797#discussioncomment-8634455 This discussion suggests that when dealing with user input in a Combobox, it might be safer to leave the input and provide an error message if the user forgets to select an option they typed.

• https://github.com/twilio-labs/paste/discussions/2885#discussioncomment-7017076 The issue here was resolved by ensuring that the required property works correctly with both Combobox and MultiselectCombobox components.

• https://github.com/twilio-labs/paste/discussions/2851#discussioncomment-4267527 This discussion explains that browser validation does not apply to Combobox components due to their complex interactions. It suggests building custom field validation and using the HelpText component to display error messages, with additional guidance available in the documentation.
