[Container image] Change base image for release (#829)

## Summary

Changes the base image from alpine to debian.
Potentially unblocks `heighliner`. 

## Issue

Removes the need for `gcompat` - `glibc` compatibility layer for `musl`.

## 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
- [x] Code health or cleanup
- [ ] Documentation
- [ ] Other (specify)

## Testing

Executed build targets, built image, checked `poktrolld`.

Steps to reproduce:

```
make proto_regen
make cosmovisor_cross_compile
make ignite_release
make ignite_release_extract_binaries
docker build --no-cache --progress=plain --platform linux/amd64,linux/arm64 -t poktrolldebian -f Dockerfile.release .
docker run -it --rm --entrypoint poktrolld poktrolldebian
```
