Adding "Default Stack" info in bitrise.yml

Description of the feature request

Now, we can not see “Default Stack” info in bitrise.yml.
So I want to see “Default Stack” info in bitrise.yml.

Use case / for what or how I would use it

We team members should use the same version of Xcode.
And in many cases, current version is the same as “Default Stack” in Bitrise.
So when I wonderd “Which is the version we use in out team?”, I want to see it in bitrise.yml in local (without checking Bitrise dashboard).

Hi @ushisantoasobu
Thank you for reaching out to Bitrise.
Can you please provide the Screenshot of the page of what you are seeing?
What browser you are using to run Bitrise?

Thanks
Chaitanya
