#### Note for [zero-installs](https://yarnpkg.com/features/zero-installs) users
If you are using the Yarn feature [zero-installs](https://yarnpkg.com/features/zero-installs) that was introduced in Yarn V2, note that this PR does not update the `.yarn/cache/` directory meaning this code cannot be pulled and immediately developed on as one would expect for a zero-install project - you will need to run `yarn` to update the contents of the `./yarn/cache` directory.
If you are not using zero-install you can ignore this as your flow should likely be unchanged.
#### Vulnerabilities that will be fixed
##### With an upgrade:

(*) Note that the real score may have changed since the PR was raised.
Some vulnerabilities couldn't be fully fixed and so Snyk will still find them when the project is tested again. This may be because the vulnerability existed within more than one direct dependency, but not all of the affected dependencies could be upgraded.
Check the changes in this PR to ensure they won't cause issues with your project.
