Remove deprecated Storybook blocks alias from Varbase Project configuration

Problem/Motivation

The Varbase Project Storybook configuration contains a deprecated webpack alias that was implemented as a temporary compatibility measure for Storybook 10. This alias is no longer necessary and should be removed to keep the codebase clean and maintainable.

Steps to reproduce

1. Locate the Storybook configuration file in the Varbase Project
2. Review the webpackFinal configuration section
3. Identify the alias mapping for @storybook/blocks to @storybook/addon-docs/blocks

Proposed resolution

Remove the following code block from the Storybook Docs configuration:

// Alias @storybook/blocks to @storybook/addon-docs/blocks for Storybook 10
// compatibility. In v10, the separate @storybook/blocks package was merged
// into @storybook/addon-docs. MDX story files that still import from
// @storybook/blocks are resolved here.
webpackFinal: async (webpackConfig) => {
  webpackConfig.resolve = webpackConfig.resolve || {};
  webpackConfig.resolve.alias = {
    ...webpackConfig.resolve.alias,
    '@storybook/blocks': _require.resolve('@storybook/addon-docs/blocks'),
  };
  return webpackConfig;
},

After removal, verify that Storybook Docs renders correctly without any regressions.
