Upgrade react-syntax-highlighter in order to delete security issue about prismjs

[jing-chen1]

Describe the bug

Could we upgrade react-syntax-highlighter to its latest version 15.4.5?
It is causing security issues in our repository with prismjs CVE-2021-3801

We need prismjs major to 1.25.0

I also need the prismjs upgrade, so I have been investigating.

These PRs are necessary but not sufficient:

• Upgrade react-syntax-highlighter to pick up security patch upstream in highlight.js #17100
• Upgrade react-syntax-highlighter to pick up security patch upstream #17116

In addition, 5.3 @storybook#addon-storysource needs to upgrade the version of react-syntax-highlighter. I have added that to 17116.

Also, the @storybook/design-system used in both the next branch and 5.3 branch needs an upgrade.

Crikey!! I just released https://github.com/storybookjs/storybook/releases/tag/v6.5.0-alpha.11 containing PR #17127 that references this issue. Upgrade today to the @next NPM tag to try it out!
