(education) "add your project to the Umap"

The education page should tell viewers to share their projects with us so we can add them to the map.

The Umap can currently only be edited by me (which should be another discussion).
I also have a shared (private) spreadsheet that I try to keep up to date with all known projects, links, etc
Many of them are not yet referenced on the Umap due to the lack of information available.

The current format is as follow:

• Project Name
• Country, City
• Organization
• person in charge
• contact
• Date / duration
• current state (ongoing, finished, R&D, ...)
• type/subject
• tech used outside Minetest? (Arduino, ...)
• URL / link
• git depot
• text presentation (around 250 / 350 characters)

This could be turned into a form at some point.

We could add a text right below the map inviting educators to share their project, with a link to, either:

• the contact area (and they'll have to ask around on their preferred platform)
• a forum post (requires forum registration, and I don't monitor it)
• the Edu Discord (requires Discord registration, but I'm there, as well as many other educators)
• an email address (without a specific list of what's needed, data might be unusable, but we would have their email address to ask further questions)
• a form sent to an email address (best in term of usability and data quality, but requires implementing a form or using 3rd party form)

Start with the education page and review the map section and the listed contact options. Confirm which submission route and required project details are approved; done means the page clearly invites educators to submit projects and provides the chosen link or address.
