KiCad nightly (v5.99): New schematic and symbol library file formats are now the default

The new schematic file and symbol library file formats are documented. At some point, these documents will be converted into formal documentation and added to the developer documentation. You really shouldn’t need documentation. One of the goals of all KiCad file formats is human readability so if you cannot understand reading a file without documentation, then we have failed on that front.
