[wktk]

Changes

To fix the installation issue on TypeScript with yarn since v4.4.0, added the following changes:

• Use the add subcommand to add dependencies
  • While npm and pnpm support both install and add for adding dependencies, yarn requires to use add to do it.
• Fixed a minor typo
• Add .changelog
