Subject: [PATCH] Make tree-sitter-cli check fail instead of continuing

Currently, the tree-sitter-cli check passes instead of failing
even when the executable is not	found which leads to a build
failure.

```
[1/5] Generating parser.c
FAILED: [code=127] tree-sitter-cpp/src/parser.c
cd tree-sitter-cpp && TREE_SITTER_CLI-NOTFOUND generate src/grammar.json --abi=14
/bin/sh: line 1: TREE_SITTER_CLI-NOTFOUND: command not found
```
