This PR was automatically created by Snyk using the credentials of a real user.

Snyk has created this PR to fix one or more vulnerable packages in the `yarn` dependencies of this project.

#### Changes included in this PR - Changes to the following files to upgrade the vulnerable dependencies to a fixed version: - package.json #### 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.

⚠️ Warning

``` Failed to update the yarn.lock, please update manually before merging. ```
