Force override prismjs to 1.30.0 to mitigate vulnerability

The vulnerability: GHSA-x7hr-w5r2-h6wg

The current package transitive dependency route looks like:
[email protected] -> [email protected] -> [email protected]

Even the latest version of react-syntax-highlighter (15.6.1) continues to
depend on 1.27.0 so there's not a lot that can be done other than patching upstream.

This commit also removes some overrides that were introduced during the nextjs
update, that don't seem to be required.
