- Restores the Yarn Berry v4 migration that was previously reverted
- Updates project to use Yarn 3.6.4 instead of Yarn Classic v1.22.22
- Addresses Red Hat policy requirements for phasing out Yarn Classic
- Enables hermetic builds with Konflux Hermetic support

Changes Made:
- Restored .yarn/releases/yarn-3.6.4.cjs - Yarn Berry executable
- Restored .yarnrc.yml - Yarn Berry configuration with hermetic settings
- Updated .gitignore - Added Yarn Berry patterns (.pnp.*, .yarn/cache, etc.)
- Updated Dockerfile - Modified build process for Yarn Berry (Node.js 18)
- Regenerated yarn.lock - Converted from Classic to Berry format
- Fixed webpack configuration conflicts

Testing:
- yarn install - Dependencies install successfully
- yarn build - Build completes successfully with same warnings as v1
- All existing functionality preserved

Context:
This un-reverts the changes from PR migtools#1543, which previously reverted
the Yarn Berry migration from PR migtools#1538. This migration was completed
before but reverted due to temporary issues that may now be resolved.

Policy Compliance:
Addresses Red Hat policy requirements:
- PSS.SBR.02.03 - Hermetic builds
- PSS.SBR.02.04 - Central Artifact Registry support
- End of Q1 2026 deadline for Yarn Classic migration
