The documentation for filtering variables in webapps should be aligned to the Rest API docs. Currently, when filtering variables in Process Definition, Process Instance Views, and Dashboard, the supported types are String, Number or Boolean.

• https://docs.camunda.org/manual/7.10/webapps/cockpit/bpmn/process-definition-view/#filter
• https://docs.camunda.org/manual/7.10/webapps/cockpit/bpmn/process-instance-view/#filter-for-variables
• https://docs.camunda.org/manual/7.10/webapps/cockpit/bpmn/dashboard/#search

Please verify that the other filters are documented correctly.
