Bump serialize-javascript dependency

[dappjumper]

Description

NPM Audit produces High-severity alert for a vue-server-renderer called serialize-javascript

This can be fixed on projects by adding

"serialize-javascript": ">=3.1.0"

To my project's package.json, but it should be done on gridsome itself, not for every new project using gridsome

Steps to reproduce

Create any gridsome cli app and try running it

Expected result

No high severity issues out-of-the-box

Actual result

High severity issue out-of-the-box

I noticed the security message earlier today. A PR for upgrading it was merged in vue-server-renderer some hours ago. You should be able to update your lock file once they have publish a new version :)
