Lots of link fixes (#1145)

Did a quick "rake test" as a follow-up on the last merge, just to see if there were any issues. Turns out there were over 300. So I went through and fixes broken links and file references.

Some of those must have been in there for a long time. Which is weird, because I do run the script here and there.

+There’s never really been an easy, let alone fun, way to get people engaged with bitcoin tech. That was until [Saving Satoshi](https://savingsatoshi.com), a light-hearted, interactive role-playing game (RPG) that functions as a first point of contact for coders learning bitcoin development.
 
 Saving Satoshi uses storytelling and game mechanics to onboard curious developers into bitcoin tech and the ₿OSS (bitcoin open source software) ecosystem. With fun, innovative challenges, it’s designed to be a gentle and welcoming entry point for those wishing to go deeper into the world of bitcoin development. From address derivation to block template construction, players are introduced to a variety of technical topics over the course of ten chapters, each filled to the brim with challenges, simulations, and coding exercises. Beginning with basic concepts like hashing and using a block explorer, learners quickly advance to more difficult material that ultimately culminates in the lightning network.

-In October 2022, the Bitcoin Design Community organized its first [Designathon](http://event.bitcoin.design), in collaboration with the first Bolt.fun Legends of Lightning hackathon. Adam Jonas of [Chaincode Labs](http://chaincode.com) proposed the initial idea of Saving Satoshi, which was very close to what the project came to be. Take a look back in [this recording](https://www.youtube.com/watch?v=b5Fw0HIqZDM) of the first call the group had together.
