📌(dependencies) update yarn.lock to deduplicate @type/react versions

There is currently an issue in yarn where it fails to deduplicate
dependencies versions on `yarn install`. See this issue:
yarnpkg/yarn#6070.

This, coupled with a change in the definition of Component in
@types/react, (DefinitelyTyped/DefinitelyTyped@9039892)
breaks us as it forces us to use incompatible versions of @types/react.

We can easily solve this by unlocking all our dependencies (by
deleting node_modules & yarn.lock) and regenerating the lockfile
from scratch. This is stable as it does not create a different
lockfile than what yarn does on its own.
