Configure npm with legacy peers

NOTE: If you create your package-lock.json file by running npm install
with flags that can affect the shape of your dependency tree, such as
--legacy-peer-deps or --install-links, you must provide the same flags
to npm ci or you are likely to encounter errors. An easy way to do this
is to run, for example, npm config set legacy-peer-deps=true
--location=project and commit the .npmrc file to your repo.
