ci: add renovate configuration

Since we have a lot of pin dependencies renovate will help us automate dependency updates.

`source-map` is listed as ignored as at the moment we cannot update this since their API changed to async and and this repos Code Coverage is sync.

`webpack-subresource-integrity` - the newer version requires peerDependencies that we don't want to include.
