Schema errors for eca.eca.eca_lib_0028

Well, this is a challenge now:

The format of the config entities has changed, and also some config keys have changed. Looks like for a while we have to provide all the samples in two flavours, one for ECA 2 and a new one for ECA 3.

With recipes, we can achieve that with versioning, so that their composer requirements rely on different ECA versions, and therefore composer will then always load the correct one.

As for the archives in the ECA Guide, this won't be possible the same way. For that, I wonder if we should just remove them and let people only use recipes? That would it make much easier for to maintain, and the usage should also be far less error-prone.

What do you think?

I agree, removing the archives (the Download links) makes sense.
A «composable» paradigm, we now live in… ;^)

I tested the recipe for «Access to form fields with tokens» (eca_lib_0029). The good news is that the schema warnings are gone. But I see 2 remaining issues:

FIRST ISSUE
In the ECA Library, the first command is incorrect:

## Import recipe
composer require drupal/eca_lib_0029

This is the correct command:

## Import recipe
composer require drupal-eca-recipe/eca_lib_0029

SECOND ISSUE
There is an issue with the property panel.

I've fixed the namespace in the packages and in the ECA Guide Library.

The property panel is an Ajax issue with Drupal core where it sometimes loads into a non-modal dialogue instead of the off-canvas panel. After a page reload, this is always fixed. It doesn't happen often, but i couldn't figure out yet, how to reproduce, and then also fix it. If anything, this would be something to work on in the bpmn_io module, not really ECA.

Looks good, setting to RTBC
