Marketplace plugin loading fails due to invalid schema on multiple plugins

Description

When loading the official marketplace plugins, several plugins fail schema validation due to invalid "source" fields, causing them to not appear in the available plugins list.

Error Message

Showing available plugins.

Impact

Plugins at indices 56, 63, 67, 71-75, and 81 are not shown to users because they fail validation. Users expecting to see these plugins won't find them in the available plugins list.

Expected Behavior

All marketplace plugins should have valid schema definitions and appear in the plugins list.
