Neo4j backup fails with azure-cli version 2.34.1

[coy2k]

Describe the bug
Backup job fails uploading blobs to azure storage because existing ones cannot be overwritten due to a storage braking change in azure-cli version 2.34.1

To Reproduce

1. Build neo4j backup docker image
2. Deploy backup helm chart using the new docker image
3. Trigger the backup cronjob

Expected behavior
Backup job finished OK

Error Logs
"ERROR: The specified blob already exists."

Additional context
Installed azure-cli version is not fixed in the backup Dockerfile:

RUN curl -sL https://aka.ms/InstallAzureCLIDeb | bash

backup.sh should be updated to add --overwrite option when needed:

      echo "Azure storage blob copy to $CONTAINER :: $latest_name"
      az storage blob upload --container-name "$CONTAINER" \
                             --file "$backup_path" \
                             --name "$latest_name" \
                             --account-name "$ACCOUNT_NAME" \
                             --account-key "$ACCOUNT_KEY"
