Change introduction to reflect platform is wider than GeoERA

Summary

http://egdi-public.gitlabpages.geus.dk/egdi-documentation/#/README has

paragraph one:

The EGDI platform has dual purposes. One purpose is to make data from the GeoERA Scientific projects (GSP’s) available and easy to use for different types of users. The other purpose is to secure that the same data will be available after the end of the GSP’s.

paragraph five:

In some cases delivering data by services is needed. This is the case for data from online censors delivering data about the hydraulic head from boreholes. These data comes from national monitoring programs where new data are added on a regular base and where the data flow can be maintained in the years after the end of the GeoERA project.

Details

Change references or broaden description for projects beyond GeoERA (and GSEU). Note too there is a typo 'censors' instead of 'sensors' in paragraph 5.
