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
- yarn.lock
#### 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:
