Currently, a symbol listed in both `supertypes` and `inline` produces a phantom supertype entry in `node-types.json` for a rule that can never appear in a tree. `intern_symbols` now drops the supertype with a warning. A hard error would break 29 published grammars, including python, go, ruby, rust, and scala, so that that decision is deferred to the next breaking release. Fixes #5218 |

tree-sitter
Tree-sitter is a parser generator tool and an incremental parsing library. It can build a concrete syntax tree for a source file and efficiently update the syntax tree as the source file is edited. Tree-sitter aims to be:
- General enough to parse any programming language
- Fast enough to parse on every keystroke in a text editor
- Robust enough to provide useful results even in the presence of syntax errors
- Dependency-free so that the runtime library (which is written in pure C) can be embedded in any application
