chore: improve preload comment

[yangannyx]

Simple text change to the comment at the top of the the default preload.js file. Clarifies what the preload script runs before.

coverage: 87.245%. remained the same
when pulling b8c52a1 on yangannyx:anny/better-preload-comments
into 4bf7ed9 on electron:main.

Thanks for the PR! Agreed the current wording is less than ideal.

The content in Fiddle actually gets loaded from electron/electron-quick-start by looking for a branch there (e.g. 29-x-y) and using the content there first. The file you've touched in Fiddle is the fallback if the other is not found.

As such, let's first make this change in that repo so that these don't diverge, and then we can land it here.

Thanks for the pointer! Made the same change to electron/electron-quick-start here

Changed the title to be chore: rather than fix: as I think that's more accurate in this case.
