chore: revert "bump webpack from 5.94.0 to 5.105.0 (#13040)"

[ilhan007]

Reverts #13040 - webpack 5.105.0 breaks playground-elements at runtime

• Before (5.94.0): Webpack would statically analyze import.meta.url patterns and either:

  • Transform them at build time
  • Leave known patterns alone for runtime resolution

• After (5.105.0): Webpack now defers unknown import.meta property resolution to runtime.
  This change causes webpack to:

  • Attempt to resolve the URL https://unpkg.com/playground-elements@0.18.1/ as a module specifier
  • Fail because it's not a valid module path in the bundle

The Breaking Pattern

// This pattern in playground-elements:
const baseUrl = import.meta.url;  // "https://unpkg.com/playground-elements@0.18.1/..."
import(baseUrl + 'some-file.js'); // webpack now tries to resolve this as a module
