Regarding $SSH_PRIVATE_KEY and $SSH_PUBLIC_KEY can you please clarify how were those created and where are referenced from (are those set as environment variables in the bitbucket deployment)?

The SSH keys are generated by Bitbucket. You can generate those in the settings of your project. The values are passed to your bitbucket pipelines as environment variables. Also see https://support.atlassian.com/bitbucket-cloud/docs/using-ssh-keys-in-bitbucket-pipelines/
