overwrite babel/runtime version

[hugosolar]

Description of the Change

Due to a vulnerability, we need to overwrite @babel/runtime package. This package is a dependency from several @WordPress core packages and it seems like there's an ongoing discussion around this topic but it's not expected to be fixed soon. Because of that we're adding an overwrite to package.json
Also noting that dependabot tried to fix this here https://github.com/10up/ElasticPress/security/dependabot/83 but cannot

How to test the Change

• Clone the repo
• run npm install
• validate node_modules/@babel/runtime is the expected version: 7.27.6
