Upgrade puppeteer about mermaid-cli HOT 1 OPEN

We haven't yet upgraded Puppeteer because we're on the latest version that still supports Node.JS v14 and v16, but we're planning on dropping support for these older Node.JS versions in the next major v11 release, see #618

As a temporary fix, and if you don't mind dropping Node.JS v14/v16 support, you can use your package manager's override feature, e.g. for NPM, you can add the following to your package.json's overrides field:

{
  "overrides": {
    "@mermaid-js/mermaid-cli@^10.6.1": {
      "puppeteer": "^21"
    }
  }
}

from mermaid-cli.
