Drupal 9.3 now provides a generic EntityBundle condition, that is exposed for each entity type with bundles through a deriver.
The existing condition has been deprecated and is indicated in the title as "Content types (Deprecated)". Block visibility conditions have been updated automatically but in a number of cases, developers and site builders need to update their configuration manually until Drupal 10:
* Default configuration in modules and install profiles needs to be updated to use the new plugin ID
* Other modules that are using condition plugins need to be either updated manually or provide an upgrade path themself.
Note that the conditions are only visible if an entity is provided as context for the given entity type, which core still only does for nodes.
