chore: add .npmignore file and update package.json to include specific files in the "files" field

The .npmignore file is added to the project. It currently includes the file "out/github-action.cjs" to be ignored when publishing the package to npm.

In the package.json file, the "files" field is updated to include the files "out/cli.cjs" and "out/tiktoken_bg.wasm". This ensures that these files are included when publishing the package to npm.

The "deploy" script in the package.json file is also updated to include pushing tags to the remote repository using "git push --tags". This ensures that the newly created version tags are pushed along with the code changes.
