[BE] Remove outdated script to check namespace BC (#151453)

Browse Source 
Now that we have bc_lint in CI, this script is no longer needed (nor has it ever been conclusive). I've already updated the Runbook to not need this script.

Suppressing bc_lint as this script is not shipped as a part of torch--it is not user facing! For context, this script is (rarely) used by the release notes manager to ensure BC across releases. It had been broken for at least since 2.6.
