Update the build process to use the latest LTS version of Node.js

[gateremark]

Is your feature request related to a problem? Please describe.
The current build process for Azure Static Web Apps uses Node.js version 16.20.2, but Next.js requires a minimum version of 18.17.0. This results in build failures for Next.js-based applications deployed to Azure Static Web Apps.

Describe the solution you'd like
I would like to request that the build process for Azure Static Web Apps be updated to use Node.js version 18 + (or the latest LTS version) when building Next.js applications. This would allow Next.js-based applications to be successfully built and deployed to Azure Static Web Apps without encountering version incompatibility issues.

Describe alternatives you've considered
As a workaround, I've found 2 solutions that work:

1. I've added a step to my GitHub Actions workflow to manually set the Node.js version to 18 before running the build.
2. I've specified the Node version I require in my package.json file with the engines property.

"engines": {
      "node": ">=18.7.1"
  }

Both solutions resolve the issue, but it would be better if the build process handled this automatically for all Next.js-based applications.

Additional context
Successful Build after the workarounds above:
