Move demo and new install to Drupal 11

"example" MR is was for a live demo of Gitlab live editing - nothing to see there.

You know this, but just documenting after I did a test update: the upgrade of lupus-decoupled-project still needs D11 compatibility of

• services_env_parameter - this is on us.
• rest_menu_items - I'm guessing they want to make the test(s) work with Gitlab at the same time.

Also, the lupus_decoupled_drupal_example module included in the repo needs D11 compatibility.

I created a PR: https://github.com/drunomics/lupus-decoupled-project/pull/6

Sadly, this upgrade brings breaking changes (it requires a manual step for existing projects) to the project due to the necessary mariadb upgrade from 10.3 to 10.6. I had to start ddev with old version of mariadb and afterwards run ddev debug migrate-database mariadb:10.6 to get everything up and running.

Thank you. I re-tested for your remark and think this is fine (commented why in the github PR). So I felt confident enough to merge it.

I tested the gitpod link on the project page, and it starts Drupal 11 now.

This means this issue is done, right? Just doublechecking...

---

The frontend home URL for the gitpod demo stll starts with a single "home" link (referring to itself), no link to log in, and only a message

You are not authorized to access this page.

This is what I have gotten used to, on my local dev environment, and I didn't know whether it was just my local install...

But I guess the followup to do something about it, is #3473237: Add Login link toggle to demo frontend...

Well maybe I should add upgrade path into the readme somewhere (set mariadb to 10.3 in ddev config, ddev start and then ddev debug migrate-database mariadb:10.6 ).

That's what I initially thought and why I tested. But since I saw that DDEV actually says this by itself, I personally don't think it's really necessary.

Oops: I was too quick. Just discovered that the project type needs to be updated too. See https://github.com/drunomics/lupus-decoupled-project/pull/7 (as yet unmerged).
