After running `yarn set version berry` and `yarn install`, the file `.yarn/install-state.gz` is created.

The documentation at https://yarnpkg.com/advanced/qa#which-files-should-be-gitignored mentions that this file should be ignored:

> .yarn/install-state.tgz is an optimization file that you shouldn't have to ever commit. It simply stores the exact state of your project so that the next commands can boot without having to resolve your workspaces again.

The documentation has a minor error; the generated file is `.gz` instead of `.tgz` (source: https://github.com/yarnpkg/berry/pull/998/files#diff-23dd4c2e823c25186f1107e88e962032R201)

Similar to #2608, it's the defacto tsc way now for adding typings locally.

Node.gitignore build/Release Compiled binary addons: http to https

This adds ignores for the `yarn-debug.log*` and `yarn-error.log*` files sometimes produced by the [Yarn package manager](https://yarnpkg.com).

Some .gitignore parsers interpret directory vs non-directory patterns strictly (e.g. monochromegane/go-gitignore), so a `node_modules` pattern would not necessarily match against a real `node_modules` directory. It's generally safe to add a trailing slash to directory .gitignore patterns.
