Rename: Change YaOS to SentientOS

I found out that YaOS was already taken by a couple of other projects
on Github. Therefore, choose a unique name.

 This projects makes my dream come true - write my own operating system. I'm doing this mostly for fun, so don't expect a fully-fledged operating system on basis of the RISC-V architecture.
 Exactly like [SerenityOS](https://github.com/SerenityOS/serenity) this project doesn't use third-party runtime dependencies. If third-party dependencies are used, then only for the Build.
