Why manual recursion?
- Due to tree-sitter grammar not supporting recursion in query
(https://github.com/tree-sitter-grammars/tree-sitter-lua/issues/24),
currently only manual recursion is possible (refer to
https://github.com/projekt0n/github-nvim-theme/pull/250/files).

<br/>

Unable to highlight when simple structures appear before complex
structures, example:
```python
def t() -> str | dict[int, dict[int, dict[int, str]]]:
    pass
```
Because complex structures are parsed as `subscript` rather than
`generic_type` by tree-sitter in this case ☹
