[compiler:chore] fix SSA pdf reference link (#29162)
## Summary This PR fixes the deadlink in the SSA comment. Previously the attached link is down now. ## How did you test this change? 1. I can confirm the PDF in the new link is the same as the old now. Reference: https://www.recompiled.dev/blog/ssa/ 2. I can confirm the old link is down, and it is [not just me](https://downforeveryoneorjustme.com/pp.info.uni-karlsruhe.de?proto=https) <img width="580" alt="image" src="https://github.com/facebook/react/assets/2883231/eeca5eda-6f61-4ac4-a113-1b04370533d9"> --------- Co-authored-by: Jan Kassens <jkassens@meta.com>
