chore: migrate from deprecated upload-artifact

[bashmish]

What I did

1. Migrated from upload-artifact@v3 to upload-artifact@v4, it contains breaking changes, so I updated accordingly
   upload-artifact@v3 was deprecated in November 2024 and completely stopped working in one of recent PRs failing the build, so I needed to do that to bring Storybook Builder tests back to a working state
2. Combined Linux & Windows builds of Storybook Builder into a matrix, just saw an example how to do that keeping the flow the same, so DRYed it
3. Bumped Node to 22 in Storybook Builder tests
