chore(api-docs): bump Docusaurus to 3.10.0 and patch transitive CVEs

Upgrades @docusaurus/core and related packages from 3.4.0 to 3.10.0 and adds
npm overrides for serialize-javascript, lodash, and webpackbar to clear the
remaining high-severity transitive vulnerabilities flagged by Snyk
(node-forge, svgo, minimatch, brace-expansion, serialize-javascript RCE,
lodash prototype pollution). npm audit now reports 0 vulnerabilities and
docusaurus build succeeds.
