task: #3621449 Temporarily remove Entity Clone until it has a stable release

Closes #3621449.

Problem

drupal/entity_clone has no stable release: the 2.x branch is beta only. A project on Composer's default minimum-stability: stable therefore cannot install this recipe, which blocks the Varbase site templates on Drupal CMS:

drupal/entity_clone ~2 -> found drupal/entity_clone[2.0.0-alpha1, ..., 2.2.0-beta1] but it does not match your minimum-stability.

What changed

• composer.json: removed the drupal/entity_clone: ~2 requirement.
• recipe.yml: removed entity_clone from the install: list.

This removal is temporary

We asked the Entity Clone maintainers for a stable tag in #3189738. Once a stable 2.x release exists, this change is reversed and the dependency comes back.

Sites already running Entity Clone keep it: Composer simply stops requiring it, and the recipe stops installing it on new sites.
