fix(bisect): Adjust bash script for Ubuntu 24.04

Newer git versions gives:
  error: cannot delete branch 'earliest' used by worktree
if branches involved in bisect are to be deleted before bisect ends.

+ Remove comment about reliably deleting branches after failure,
  as having them may be useful for debugging (and does not matter in CI).
+ Move branch cleanup to the start, and allow it to fail in CI.
