“The WordPress open source community cares about diversity. We strive to maintain a welcoming environment where everyone can feel included.”
With this commit, all occurrences of “whitelist” and “blacklist” (with the single exception of the `$new_whitelist_options` global variable) are removed. A new ticket has been opened to explore renaming the `$new_whitelist_options` variable (#50434).
Changing to more specific names or rewording sentences containing these terms not only makes the code more inclusive, but also helps provide clarity. These terms are often ambiguous. What is being blocked or allowed is not always immediately clear. This can make it more difficult for non-native English speakers to read through the codebase.
Words matter. If one contributor feels more welcome because these terms are removed, this was worth the effort.

These annotations make it clear to the reader of a JavaScript source
where the build process outputs to. These annotations can later be
integrated in a webpack configuration. This way there is one source of
truth.
The `build` folder is omitted from the paths, because a single JS file
shouldn't not be responsible of knowing where outputs in general will
end up at. A file only knows its output location relative to the
project.

- really disables buttons when they look disabled (when navigation is at the first or last theme)
- when navigation is at the first or last theme, moves focus to the other navigation button, to avoid a focus loss
- improves the buttons visually hidden accessibility text

For a number of years, the "Available Widgets" section has been off-limits for
keyboard users. Now it can be used also with the keyboard. This change introduces
also some improvements for assistive technologies.
- makes the widget toggles focusable and adds an `aria-expanded` attribute to indicate their state
- improves the toggles labelling to clarify context (add/edit)
- changes the controls to choose a sidebar from list items to buttons
- adds an `aria-label` attribute to the buttons to clarify their purpose
- adds an `aria-pressed` attribute to the buttons to indicate which one is selected
- improves color contrast of the selected button
- uses a `wp.a11y.speak()` message to announce to screen reader users when a widget has been added to a sidebar
- moves focus back to the toggle button when closing a widget

Trigger a keyup event when clearing the search field in response to closing the add item panel. The keyup event triggers a search and resets the results. Previously, the search field was cleared while the potentially blank search results were left in place making it impossible to select new menu items.
