Have you read the Contributing Guidelines on issues?

• I have read the Contributing Guidelines on issues.

Prerequisites

• I'm using the latest version of Docusaurus.
• I have tried the npm run clear or yarn clear command.
• I have tried rm -rf node_modules yarn.lock package-lock.json and re-installing packages.
• I have tried creating a repro with https://new.docusaurus.io.
• I have read the console error message carefully (if applicable).

Description

The hash links (the invisible markers immediately following each heading) are throwing contrast errors. If you add an aria label of hidden, it should fix that. (see attachment)

Reproducible demo

No response

Steps to reproduce

You can see the error by installing the WAVE extension in Chrome and enabling it (click the little W button in the header) when you're on one of the Docusaurus pages which have headers (e.g., https://docusaurus.io/docs)

Expected behavior

Expect to not get any of the errors in the scans.
