Add extra text to DUA

[DorienHuijser]

closes #63

Could still be added:

• After termination, the user(s) is/are required to remove (all elements of) the data from their own storage and to make certain that no third parties have access to the data. A notification to the provider(s) is also required.
• <Country's> law applies to this agreement. Disputes will only be submitted to the district court in The Hague, but not before the parties have made an extreme attempt to settle their dispute in another way. of course this may not be feasible for an international template

This last point relates to the lawfulness of the agreement: does law apply to this DUA? Officially, (personal) research data are property of the institution (at least in NL, not sure about other countries) and thus a specific person has to sign such an agreement (usually not researchers themselves). Should there be text about this on the DUA page as well?

these would be ok - but i'd try minimize change in order because there is 18 translations to change

@DorienHuijser are you planing to continue working on this PR? E.g. to minimize changes to make it feasible to review the diff. I will change it to draft mode for now.

@yarikoptic I haven't looked at this PR in 2,5 years so I have no particular plans for it haha. I'll leave it up to you to decide whether to merge or not. If you want, I'd be happy to look over the current version of the DUA and see if I have any additions to make, but that would probably be easier if I started from scratch.
