Remove branch confirmation dialog

• Zendesk ticket: https://gitlab.zendesk.com/agent/tickets/9681
• Dev link: None
• GitLab version: Unknown

Expected behavior

To avoid deleting the wrong branch, the dialog should have the branch name in it.

Observed behavior

The dialog only says, "Removed branch cannot be restored. Are you sure?". What if user clicks on the wrong delete button?

Next steps

How hard is it to add the branch name to the dialog?
