Update Electron Typescript Example with Best Practices

[Dylan700]

Adding or Updating Examples

• The "examples guidelines" are followed from our contributing doc https://github.com/vercel/next.js/blob/canary/contributing/examples/adding-examples.md
• Make sure the linting passes by running pnpm build && pnpm lint. See https://github.com/vercel/next.js/blob/canary/contributing/repository/linting.md

What?

I am updating the Electron Typescript example based on the latest best practices from electron. Packages have also been updated to their latest version.

Why?

The current example is outdated and does not meet security best practices.

How?

Updating dependencies and improving default security setup.

Relates to #44552

Hi @leerob, just made a new PR with the latest best practices. It seems not a lot has changed, but I've upgraded dependencies etc.

I was hoping to add a content security policy here too, but it seems that because the production build exports to static html, it makes the implementation of nonces difficult.

Apologies @leerob, it seems I forgot to run the lint after those changes! I've just updated the PR now, thanks heaps.
