Only show the yoast analysis task if it has been configured to do so

Problem/Motivation

The Yoast Analysis task is now available for all entities and bundles. We want the analysis only on specific bundles of an specific entity.

Proposed resolution

If an entity bundle has the yoast_analysis view mode configured the task is shown.

Remaining tasks

There can be other solutions to this problem, for example a settings page where you specify the entities and bundles that have to show the analysis.
