Remove dependency on npm Origam plugins

Html client application still dependes on these plugins stored in npm:

    "@origam/plugin-audit": "^2.0.2",
    "@origam/plugin-chart": "^2.0.4",
    "@origam/plugin-filter": "^2.0.2",

They should be removed because the way of including plugins in origam build has changed. The projects that depend on these should include them in their custom build.
