[qvalentin]

this node type was removed in https://github.com/ngalaiko/tree-sitter-go-template

fixes #18

For now this will break the support for else if for people not using the latest (main) version of nvim-treesitter

Poem

🐰 An "else if" once troubled the tree,
But now only "else" we decree,
The parser is mended,
The conflicts now ended,
Helm templates flow smooth as can be! ✨
