Fix: update comparison page to use PNPM's up-to-date repo (#631)

**Summary**

Fixes #372 by redirecting the `/compare` page to PNPM's benchmark
repo. Until we have a contionously running benchmark suite for all
package managers, this is a good enough solution that provides a lot
more recent stats.
