Need to check with Storybook folks to see that this doesn't break coverage reports there. This was used to exclude *.stories.* from appearing in coverage report.

[AriPerkkio]

*.stories.* are now visible on coverage report 😢

[sheremet-va]

Storybook can now exclude story files inside the configureVitest hook

[AriPerkkio]

Yep, that works! Using this in fresh Storybook project fixes the issue:

      {
        name: "exclude-stories",
        configureVitest(context) {
          if (context.vitest.config.coverage.enabled) {
            context.vitest.config.coverage.exclude.push("**/*.stories.**");
          }
        },
