title13-05-2021 S2S documentation improvement

S2S documentation pages have been redesigned and updated to help users better understanding of model configurations and their changes since the project start. The main table in Models has now a feature Expand/collapse the table allowing quick overview of each model major changes impacting products for S2S. Also separate pages dedicated to each model have been updated so that users could identify model change to its previous version more easily. Complete overview of all model configurations since S2S project start should hopefully help users also to define their data retrievals for extended period of time and in more efficient way too.
