docs: correct aria-describedby guidance in Accessibility section

[moloko]

Description

Follow-up to #1284, addressing review feedback on that PR.

The Accessibility page told users to add aria-describedby to the anchor manually. That's incorrect: ReactTooltip already manages it. While the tooltip is shown it adds its id to the active anchor's aria-describedby (merging with any existing values) and removes it again on close — see Tooltip.tsx. A static attribute is also wrong because it would reference the tooltip element before it exists — the tooltip is only added to the DOM once it opens.

Changes

• Rewrites the Associating the anchor and tooltip (1.3.1) section to explain that ReactTooltip handles aria-describedby automatically, with a caution against setting it manually.
• Removes the manual aria-describedby from the combined "Putting it all together" example (code sample and live demo).

Verification

Confirmed on the live demo (which no longer sets the attribute) that ReactTooltip adds aria-describedby="accessible-tooltip" to the anchor while the tooltip is open and removes it on close, and that the tooltip element is only present in the DOM while open. Docs build passes with no MDX or broken-link errors.

Summary by CodeRabbit

• Documentation
  • Clarified that tooltip accessibility associations are managed automatically while tooltips are open.
  • Removed instructions to manually add aria-describedby.
  • Added guidance against static aria-describedby attributes that may reference unavailable tooltip elements.
