chore: use turbo instead of yarn workspace for CI tests

Yarn v4 with node-modules linker does not propagate root node_modules/.bin
to workspace packages. Replace `yarn workspace $PKG test` with
`yarn turbo run test --filter=$PKG` which runs from root context and
correctly resolves binaries like eslint and size-limit.
