Update build pipeline badge

[danieljurek]

Need to update the URL so this points to a more recent source of status data:

[kurtzeborn]

What does it point to now?

[danieljurek]

Today it points to https://dev.azure.com/azure-sdk/public/_build?definitionId=17

With unified pipelines (where we don't have a single client build) it might make sense to use multiple badges

Service	Status
App Config
Batch

Since the pipeline is internal, however, the results will only be viewable to those with permissions. Clicking on the badge today will take an unauthenticated user to an authentication experience.

I'm closing this out, there's really nothing to do here. Wes replace this pipeline badge with packages back as part of PR 6672 which links to the latest releases page. NET, JS and pyton have had similar changes but the only language with a pipelines badge is Python which is core only and not representative.
