add organisations in ROR

[wouteraddink]

Describe the issue
when registering for a new W3C account, you have to select your affiliation or create a new one. It appears that affiliations present in ROR are not all present in the select option

To reproduce
create a new user and try to select e.g. Naturalis (https://ror.org/0566bfb96) as affiliation

Expected behavior
all research organisations present in ROR should be known already and selectable.

Additional context
ROR is a standard for research organisation identifiers. It is a validated resource with PIDs for all research organisations. As a standards organisation W3C should make use of such standards.
