[CI] Add cosmovisor to container images (#796)

## Summary

Add cosmovisor binary to our container images. It will allow us to use
cosmovisor in
[docker-compose-example](https://github.com/pokt-network/poktroll-docker-compose-example)
repo in the future to automate upgrades.

## Type of change

Select one or more from the following:

- [ ] New feature, functionality or library
- [ ] Consensus breaking; add the `consensus-breaking` label if so. See
#791 for details
- [ ] Bug fix
- [ ] Code health or cleanup
- [ ] Documentation
- [x] Other - tooling

## Testing

No code was changed - no reason for extensive testing.

- Tested Dockerfile.release locally and Dockerfile.dev will be tested by
CI.

## Sanity Checklist

- [x] I have tested my changes using the available tooling
- [x] I have commented my code
- [x] I have performed a self-review of my own code; both comments &
source code
- [ ] I create and reference any new tickets, if applicable
- [ ] I have left TODOs throughout the codebase, if applicable
