Describe the issue you are experiencing

It appears that in the Developer Tools Actions page, when multiple examples exist for a field, and the user selects YAML mode, the examples are not comma separated, i.e. they display as alloneword.

It is potentially arguable whether an example should have more than one option at all.

However, assuming we have more than one example, they should be separated when listed.

Describe the behavior you expected

• Example yaml values displayed clearly

Steps to reproduce the issue

1. Visit /developer-tools/action
2. Select recorder.get_statistics
3. Click 'Go to YAML mode'
4. Look at 'Example' column
