feat: upgrade to USWDS 3.13.0

[mdmower-csnw]

Work in progress.

This pull request builds off of the work in #3265. When that pull request is merged, this will be rebased and moved out of draft status.

Summary

Apply updates related to features and bug fixes released by USWDS in 3.11.0, 3.12.0, and 3.13.0.

• Update default error message for file input and apply to aria-label on error
• Only show in-page navigation if minimum number of headings is found
  • Support setting minimum number of headings via props
• Include nested headings in in-page navigation
• Footer story fixes (these changes are not the reason for most Happo differences):
  • Remove incorrectly applied usa-footer__secondary-link class to footer story anchors (the class is applied by the FooterNav component to <li>)
  • Update primary link text in slim and medium FooterNav stories to match the text used in the Footer stories
  • Render only <FooterNav> for the big FooterNav variant, not with <Footer> wrapping it

Notable omissions:

• 3.12: The existing i18n support in date picker is a better option than generating locale specific calendar labels based on the HTML lang attribute since only some labels could be generated.
• 3.12: The tooltip component already supports non-button elements.
• 3.13: USWDS Elements is still in the earliest stages of support (only usa-banner for now). Dedicated attention to web components support would be best handled by a separate pull request.
