What does this PR do?

Enables Telemetry when the extension runs in a Web browser

What issues does this PR fix or reference?

No linked issue

Is it tested? How?

Best way to test this is to run a CLI build:

yarn build

Then launch an http server and create a tunnel to expose it online. In one terminal run:

npx serve --cors -l 5000

This will start a web server on port 5000. Then, in a second terminal, execute:

npx localtunnel -p 5000

This will expose your local web server to a public URL like https://<fancy-name>-<your-IP>.loca.lt
Copy that URL, open it in a browser, click on the button to enable it.

Then go to https://vscode.dev, if you already have redhat.vscode-yaml installed, uninstall it.
With the command palette (Ctrl+Shift+P/Cmd+Shift+P on mac), run the Developer: Install Extension from Location... command.
Paste your loca.lt URL

Create a new document, select YAML language, you should see the Red Hat telemetry Opt-in popup. After accepting it and you should see a startup event in Amplitude
