Use Renovate bot for updating package-lock.json

[hs2361]

Currently, because of committing the package-lock.json file, our commit diffs have a lot of noise. Furthermore, it is very difficult to resolve merge conflicts inside of the file, as it is very long. Using a bot such as Renovate might be helpful, as it can automate the process of generating the package-lock.json file every time the package.json file is changed in a commit.
