Scripts: Update sass and sass-loader packages

[jacobcassidy]

What?

Updates the sass and sass-loader dependencies used in @wordpress/scripts.

Why?

The older version of sass-loader is using a legacy API that is coming to end-of-life. See https://sass-lang.com/documentation/breaking-changes/legacy-js-api/.

The @wordpress/scripts build process also shows multiple warnings every time it runs when sass files exist. This update removes them.

How?

This updates the @wordpress/scripts package.json file as well as the main package.json and main package-lock.json files to use the most recent updated version of sass and sass-loader.

Testing Instructions

1. To test the changes, add the following to a package.json file that is using @wordpress/scripts:

"overrides": {
	"sass-loader": "^16.0.2",
	"sass": "^1.79.3"
},

2. Run: npm install
3. Run the build process: npm run build
4. See that no issues are reported

This was fixed with #67572. Tested with @wordpress/[email protected]. The stable version is expected to be published to npm on Wednesday. sass could still get enforced to more recent version in @wordpress/scripts and in Gutenberg, but it would be a complex warnings as there were many deprecations introduced that need to be addressed in the project.

@gziolo I'm overloaded right now, so I don't plan to continue working on this anytime soon.

Do you want me to close the related WP PRs that I am no longer actively working on?
