Scenario Template: syntax coloring not working

[zmorris]

Describe the bug
Scenario Template: keyword (from Gherkin 6?) not highlighting, maybe others

To Reproduce
Steps to reproduce the behavior:

1. Edit settings.json (~/Library/Application Support/Code/User/settings.json on macOS) to have:

    "cucumberautocomplete.formatConfOverride": {
        "Scenario Template:": 1
    }

2. Relaunch VS Code or disable/reload/enable Cucumber (Gherkin) Full Support extension
3. Open a file ending with .feature and see that lines starting with Scenario Template: are still the default color
4. I'm using VS Code 1.72.2 on macOS 12.5.1 if that helps

Expected behavior
Scenario Template: should be the same color as Scenario Outline:
See #293 for previous issue which is closed
See https://cucumber.io/docs/gherkin/reference/ for additional keywords
Updating the default conf to have the new keyword(s) would be enough to help me, even if overriding cucumberautocomplete.formatConfOverride still doesn't work for some reason (maybe user error on my part)
