Fix RichTextMigration tests: toolbar extraction always returning empty

[Copilot]

RichTextMigrationValueTest and RichTextMigratedValueTest both failed because the TipTap toolbar migration produced [[[]]] instead of the mapped toolbar items.

Root causes

1. Short-circuit bug: toolbar list always empty

// && short-circuits when TryGetValue succeeds — TryGetToolbarArray never called
if (configuration.TryGetValue("toolbar", out var toolbar) is false
    && TryGetToolbarArray(toolbar, out toolbarList) is false)

// Fix: use || so both conditions are evaluated
if (configuration.TryGetValue("toolbar", out var toolbar) is false
    || TryGetToolbarArray(toolbar, out toolbarList) is false)

2. TryGetToolbarArray only handled JsonElement

When config is deserialized into IDictionary<string, object> via _defaultOptions (which includes Umbraco's JsonObjectConverter), JSON string arrays come back as List<string> — not JsonElement. The method now handles both:

if (toolbar is IEnumerable<string> stringList)
{
    toolBarList = stringList.ToList();
    return toolBarList.Count > 0;
}

if (toolbar is not JsonElement jsonElement || jsonElement.ValueKind != JsonValueKind.Array)
    return false;
// ... JsonElement path unchanged

The JsonElement path is still needed for toolbar values promoted to top-level by TopLevelEditor.

<issue_title>Richtext tests fail because of array is incorrect.</issue_title>
<issue_description>Currently the RichTextMigration tests fail because they returned results has one two many levels of nested array in it for what the test expects.

I have tested locally and the methods in the code are correct and the actual json defined in the tests is incorrect. so this needs updating to match so the tests pass. </issue_description>

<agent_instructions>Create a new pr and fix RichtTextMigrations test so that they pass - assume the returned JSON from the methods being tested is correct. </agent_instructions>
