`RUST_SITTER_EMIT_ARTIFACTS=true` causes the build to fail

[Joeoc2001]

When building with RUST_SITTER_EMIT_ARTIFACTS=true, the build tool panics on my machine.

error: failed to run custom build command for `rust-sitter-example v0.4.4 (~/Documents/rust-sitter/example)`

Caused by:
  process didn't exit successfully: `~/Documents/rust-sitter/target/debug/build/rust-sitter-example-3bec39671d8b9293/build-script-build` (exit status: 101)
