Textblocks + Objects: Support for URLs without http://

[sosiology]

Is your enhancement related to a problem? Please describe.
At the moment, we support links in texts in Visualize. This is the case for both Textblocks (objects) for dashboards but also in the title and description of a single chart. To enter a link, the user is prompted to add a full link, including the https://

Describe the solution you'd like
Links should be accepted even if they do not include https:// (e.g www.visualize.admin.ch should also work, not only https://www.visualize.admin.ch) to facilitate the ease of editing.

Describe alternatives you've considered
NA

Use cases and impact
This would allow users more flexibility when adding links as there are no limitations. On the other side of the spectrum, the current approach ensure that the link entered by the user is a valid link.
