az pipelines run should give a browsable url somewhere in the output

**Is your feature request related to a problem? Please describe.**
A clear and concise description of what the problem is. Ex. I cannot create a project..

Comparing to flows:
1. `az pipelines run --name "foo" --branch refs/heads/bar --open`
2. `az pipelines run --name "foo" --branch refs/heads/bar`

Both have same effects in pipeline's run, 1st will open a browser, 2nd will not. If user want to get that browsable url – there is no way for him.

**Describe the solution you'd like**
A clear and concise description of what you want to happen.
e.g. If you want a new command to be added, what would it do?

I want the url to be in output, so I can grep it (with `jq`) and send it to smb. or open it myself.
