Add links to instructions

[arunge]

...

Additionally, we should think about

• where to put a link within the installation instructions to this known issue of "port is already allocated".
• we also need a link to the online version (respectively for each app):
  • a link for each version, main and beta? (needs to be confirmed)
  • a note such as under isomemosearch.com:
• maybe we should change the order: first the docker installation and than the R installation? What do you think, what should be default?

I will open a new issue for above points.

Let us discuss ideas next week, please!

Regarding links there is an update:

• links to the main version should be found in the wiki
• links to beta and main version should be found in the readMe, so no need to add the link to beta also to the wiki.

The idea is that users are more reading the wiki and the readMe is more relevant for developers.

Regarding the ReadMe, I have to update the readMe's regarding links to local model files, so I will add the links to the versions.

@jan-abel-inwt So, since you added all links to the main apps in the wikis already, you are done here, correct?
