Node v12.22.7 Unit Test Breaks

[Carthanial]

Description :

Below are the files(6) that have failed tests in the Jenkins Unit Test Stage for bfs7.7.1-upgrade :

• src/core/server/logging/appenders/file/file_appender.test.ts

• packages/kbn-config-schema/src/types/stream_type.test.ts

• src/legacy/server/capabilities/capabilities_mixin.test.ts

• This file is not in the documentation (from linked comment below) that I have been using.
• This is due to the Capabilities feature being moved to a new platform
• This move was done between kibana v7.7.1 and v7.11/v8.0 which are the version tags used for the PR documentation referenced below on the upgrade to node v12.

• src/core/server/http/http_server.test.ts

• src/plugins/console/public/application/models/sense_editor/__tests__/integration.test.js

• src/core/server/http/router/validator/validator.test.ts

Please refer to this comment on the approach for fixing these issues :
