feat: upgrade to USWDS 3.8.2

[mdmower-csnw]

This is a continuation of #2848 by @werdnanoslen since it doesn't look like additional movement is expected there.

Summary

These are the features released by USWDS in 3.8.0, 3.8.1, and 3.8.2:

• Added styles for indeterminate checkboxes and radios
• Added the ability to customize which headings will be pulled into the in-page navigation link list
  • Also changed class name and selection criteria for bolded heading
• Added a sticky header variant to the table component
• Updated sidenav example in documentation per new theme setting
• Made tooltip content hoverable
• Made tooltip dismissible with escape key
• Added textarea validation storybook entry
• Changed button centering from text-center to flex-justify-center since display for buttons changed from inline-block to inline-flex in USWDS - Button: Add basic support for usa-icon in buttons uswds/uswds#5398.
• Removed tooltip opacity override that was fixed by USWDS: USWDS - Tooltip: Add opacity:0 to initial state uswds/uswds#5475
• Changed button-based pagination to use <button> instead of <Button unstyled> to avoid style conflicts between usa-button--unstyled and usa-pagination__button classes (notably, hover styles). Apply minimal utility classes to align styles with link-based pagination.

No action needed to support $theme-table-background-color. It has been verified working by temporarily setting $theme-table-background-color: 'primary-vivid' in src/styles/_uswds-theme.scss and then rebuilding USWDS (yarn build:uswds) followed by running the storybook (yarn storybook).

How To Test

Confirm things work the same as described in USWDS release notes: 3.8.0, 3.8.1, and 3.8.2.

Happo differences

• Components/Search/SearchButton/Small search: Alignment of the icon in mobile layout is fixed by USWDS styles.
• Components/Search/SearchButton/* and Components/Search/Search/*: All of these very slight button height differences are the result of display changing from inline-block to inline-flex in USWDS - Button: Add basic support for usa-icon in buttons uswds/uswds#5398. Opting to allow changes.

@jpandersen87 @brandonlenz (and cc: @werdnanoslen just in case you are still active in the project) - Would you be willing to review this changeset? I think it'd be best to increment USWDS one or two minor versions at a time, rather than trying to jump to the latest revision. Plus, @werdnanoslen had this 3.8 update largely done and it would be nice to respect his contribution.

EDIT: FYI, I've started work on 3.9 (#3264), 3.10 (#3265), and 3.11+3.12+3.13 (#3266).

@crwallace - I just noticed you are listed as the active maintainer for this project in the readme. Are you able to help with reviews? Thanks!

I've also started work on 3.9 (#3264), 3.10 (#3265), and 3.11+3.12+3.13 (#3266).

This should resolve the CI failures and let us move forward with merging @mdmower-csnw.

Would love to coordinate getting these updates out with you this week if you're available for that

This looks great.

I noticed one change needed for the sticky header table story, and one potential bug/inconsistency with the Tooltip Escape key functionality

[brandonlenz]

Thanks @mdmower-csnw, this is a huge help.

I'm going to cut a quick release tomorrow of all the changes on main leading up to this, then I want to release this as a part of its own (likely 10.2.0) release, just because its been a little while since we've updated the USWDS dependency and I want to give consumers another version to easily roll back to if needed.
