Fix broken links in docs

[colinodell]

💸 TL;DR

Updates links that pointed to non-public resources

📜 Details

After attending yesterday's (awesome) KubeCon session about this library, I started combing through the docs but kept hitting broken or private links. I've therefore attempted to update those links in this PR to the best location I could determine.

Please double-check my changes here (especially in the sdk-fsm-reconciler.md file) since I haven't actually used this library yet and don't want to mislead other developers by pointing to the wrong places! 😅

🧪 Testing Steps / Validation

I manually clicked the updated links to ensure they loaded?

✅ Checks

(Karan's OOO this week so I'll take over the review) Just one minor tweak, otherwise LGTM. Thanks for these fixes!

I'm fixing CI for forked PRs here, #9 (Github Actions doesn't allow usage of repo secrets for CI running on forked PRs, but since all dependencies are open sourced now we can fully remove this configuration)

Update against main and we can rerun CI

Thanks for the review! I've applied the suggestions and updated against main.
