Include wasm files in package: manually remove .gitignore file generated by wasm-pack

[treebirg]

#272 did not have the desired result: .gitignore files in subdirectories take precedence over the files field in package.json so the wasm files are still ignored.

This change manually removes the .gitignore file generated by wasm-pack before publishing.

Below is the output of npm pack before and after removing the .gitignore file. Showing that the package should now include the required files.

~/treebirg/protoc-gen-ts/js/plugin main
❯ npm pack --dry-run
