[Console Monaco] Add theme for yaml and text mode in output

[ElenaStoeva]

Addresses #179905

Summary

This PR adds themes for the Console output panel when it is in YAML or Text mode. The main theme features that are specified for these two main modes are colors (e.g. background color).

How to test:

1. Create a config/kibana.dev.yml file (if one doesn't exist already) and add the line: console.dev.enableMonaco: true
2. Change the condition in

   kibana/src/plugins/console/public/application/containers/editor/editor.tsx

   Line 76 in b8c13ba

   ) : isMonacoEnabled ? (

   to !isMonacoEnabled to display the old Ace editor in the request panel for now so that we can test sending a request.
3. Send a request and verify that the theme for json mode hasn't changed.
4. Send a request with ?format=yaml parameter (e.g. GET _all?format=yaml) and verify that the theme (apart from the text colors) is the same as in json.

5. The output also supports text output data. To test this format, comment out line 30 and add the following code in line 34 in src/plugins/console/public/application/containers/editor/monaco/monaco_editor_output.tsx:

const data = [
      {
        response: { value: 'Hello World!' },
      },
    ];

Then reload the Console page and verify that the theme (apart from the text colors) is the same as in json:

Converting to draft as we might need to defer merging this until we resolve #180218 since this issue is related to assigning different themes in the output panel.

[ElenaStoeva]

Closing as we will use a single theme for both the editor and the output panel (see #180321).
