va-telephone message aria describedby

[Mottie]

Bug Report

• I’ve searched for any related issues and avoided creating a duplicate issue.

What happened

This doesn't appear to be an actual bug, but in storybook, the message-aria-describedby property is set to false and this leads the component to interpret that value as a string and eventually renders a screen-reader only span in the shadow DOM with the text "false". It may be a rare occurrence in actual web component usage, so it may still need to be addressed.

What I expected to happen

Don't include messageAriaDescribedBy value if set to false

Reproducing

• CSS Library version: All
• Device: (e.g. iPhone 8, Macbook): All
• Browser: (e.g. Firefox, IE 11): All

Steps to reproduce:

1. Go to va-telephone in storybook
