Add the pipeline name for custom pipelines to the email notification

Problem Definition

Currently, the automatic email notification that Bitbucket sends you when pipeline fails contains: workspace name, repository name, commit, and commit message, but not the pipeline name (for custom pipelines).

Suggested Solution

Add the pipeline name for custom pipelines to the email notification.
Business case: some users run the same tests in a test environment and in a production environment, so the only difference is the pipeline name (pipeline configuration points to the correct environment specific config to use). This is why having a pipeline name in the notification email is valuable for these teams.
