I have fixed the deps thing in this PR. Since, in the previous one, we gradually shifted from RTL to React Shallow Renderer, which is a transitive dep of React Test Renderer (Which is already installed inside jaeger-ui).
React-is is also the dep for React test renderer, so no need to install that separately.

About the @testing-library/react @testing-library/jest-dom deps, they don't need to be installed for the scope of this PR, but as we are using two functions from Enzyme, mount, and shallow. The shallow function just got replaced in this PR, the mount function still needs to use the @testing-library/react @testing-library/jest-dom deps as per the official migration guide
I have also tried migrating mount from enzyme to renderer from RTL, and it works.
So, basically, these two deps would still be installed while using the render function from RTL
