All long-term branches should be covered by a branch protection rule

[opentelemetrybot]

There are some branches in this repo which aren't covered by a branch protection rule (other than **/**).

If these are long-term branches, please add a branch protection rule to protect them from deletions and force pushes.

If these are temporary branches that aren't needed anymore, please delete them.

If the **/** branch protection rule is preventing you from deleting temporary branches, you may change the **/** branch protection rule to allow deletions once you have branch protection rules in place for all of your long-term branches.

If you don't have repo admin privileges to make these changes, please open a community repo maintenance issue.

If you have any general questions or comments about this automatically created issue, please comment on https://github.com/open-telemetry/community/issues/2765 or ping @trask on Slack.
