Add missing peer dependencies

[romdej]

Change Summary

Some peer dependencies were missing in the package.json. This resulted in warnings during the installation of the package. So I added the missing dependencies for a better developper experience. The added dependencies are:

• @babel/runtime
• algoliasearch

I've also updated the versions of the docusaurus dependencies to allow a compatibility with more versions of docusaurus.
