Switch the data collection plugin version to the latest

e-mission/e-mission-data-collection#226
is now merged and a new release
https://github.com/e-mission/e-mission-data-collection/releases/tag/v1.8.5
has been created

So we can now use the version number instead of a branch while adding the
plugin

With this commit, the initial implementation in
#1144
is done, and we can merge it
