build(deps): bump @babel/preset-env to >= 7.9.0

Node v13.13.0 introduced a change that is incompatible with `@babel/preset-env`
versions `< 7.9.0`.

See:
* nodejs/node#32351
* nodejs/node#32852
* babel/babel#11283

Bump our direct dependencies to `7.9.5` and manually cause additional bumps in
`yarn.lock` that result in all versions of `@babel/preset-env` installed in the
monorepo's `node_modules` trees being `>= 7.9.0`.
