fix: ensure trusted publishing uses npm 11 [FEPLAT-5048]

[ilan-phantom]

Summary

• remove the obsolete Semantic Release script and dependencies
• remove the transitive npm 6 binary that shadows the workflow-installed npm 11
• keep Changesets as the only release implementation

Why

The failed release run used node_modules/.bin/npm 6.14.18. That version cannot perform npm Trusted Publishing's OIDC exchange, so the publish continued unauthenticated and npm returned E404.

Failed run: https://github.com/phantom/react-native-webview/actions/runs/31612642119/job/94167581149

Validation

• frozen Yarn install
• TypeScript and ESLint
• declaration generation and Babel build
• confirmed no local node_modules/.bin/npm remains
• confirmed the release subprocess resolves npm 11 instead of npm 6

Summary by CodeRabbit

• Chores
  • Removed the automated publishing workflow and related release tooling.
