Simplify release workflow secrets configuration

Remove unused SSM parameters from the release workflow to streamline secret retrieval. This removes the following token references that are no longer needed:
- CIRCLECI_CLI_TOKEN
- BITBUCKET_USERNAME
- BITBUCKET_TOKEN
- GITHUB_RELEASE_TOKEN (via SSM)
