Several dead links in documentation

Hello,

I would like to report several dead links in various documentations across the LinkAhead project.

• At https://docs.indiscale.com//caosdb-webui/tutorials/first_steps.html#first-steps, "You can find more details here", here is a link to an invalid URL.

• At https://docs.indiscale.com//caosdb-webui/tutorials/first_steps.html, the link to the wiki points to an old repository without any wiki.

• At https://docs.indiscale.com//caosdb-webui/tutorials/edit_mode.html#new-property, there is a link in "See here for more information on the datatypes". The "here" is a link that gets redirected to an internal repository (I was not able to access it by connecting to your instance using GitLab.com SSO. My email addresses (@gmail.com) are rejected on ground that it is not authorized for account creation.
