[Snyk] Fix for 13 vulnerabilities

[jmatsushita]

Snyk has created this PR to fix 13 vulnerabilities in the yarn dependencies of this project.

Snyk changed the following file(s):

• package.json
• yarn.lock

Note for zero-installs users

If you are using the Yarn feature 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:
