Docs Updates

[coliff]

This pull request focuses on accessibility improvements, documentation updates, and minor dependency adjustments. The most significant changes enhance accessibility for close buttons in modals, clarify documentation for several components, and update some visual and dependency aspects.

Accessibility improvements:

• Updated all modal and close button examples in documentation to use a visually hidden <span> with the label "Close" instead of relying solely on the aria-label attribute. This ensures better accessibility for screen readers. (site/content/docs/v2/components/close-button.md, site/content/docs/v2/components/modal.md) [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] [14] [15] [16] [17] [18]

Documentation updates:

• Added guidance for making .list-group-item-action elements appear disabled and accessible by adding .disabled and aria-disabled="true". (site/content/docs/v2/components/list-group.md)
• Updated Popper.js documentation links to point to the latest v2 docs and clarified keyboard interaction language. (site/content/docs/v2/components/dropdowns.md)
• Adjusted dropdown button example to use btn-secondary for visual consistency. (site/content/docs/v2/components/dropdowns.md)

Visual and dependency updates:

• Updated the search icon in the navbar to use a newer version of the Modus icon set. (site/assets/scss/_navbar-search.scss)
• Downgraded the eslint-config-xo dev dependency from 0.49.0 to 0.45.0. (package.json)

Minor content and formatting tweaks:

• Fixed minor typographical and formatting issues, such as using typographic apostrophes and self-closing image tags. (site/content/docs/v2/components/modal.md, site/content/docs/v2/components/chips.md) [1] [2] [3]
