Update text in terms of use in VUGs for clarity

[ahernank]

Update the first paragraph of the terms of use in each release page from:

Data from this project will be made publicly available before journal publication. Unless otherwise stated, analyses of project data are ongoing and publications are in preparation by project partners, and it is not permitted to use project data for publication (including any type of communication with the general public) without prior permission from the originating partner studies.

To:

Data from this project will be made publicly available before journal publication, subject to the following publication embargo: unless otherwise stated, analyses of project data are ongoing and publications are in preparation by project partners, and it is not permitted to use project data for publication (including any type of communication with the general public) without prior permission from the originating partner studies. The publication embargo will expire 24 months after the data is integrated into the Malaria Genome Vector Observatory data repository, or earlier, if the project partner agrees to remove the embargo before the expiry date.

To note: the terms of use haven't changed, this is just a re-write to ensure clarity.
