Bump kamal from 1.5.2 to 1.6.0

[dependabot[bot]]

Bumps kamal from 1.5.2 to 1.6.0.

Release notes

Sourced from kamal's releases.

v1.6.0

What's Changed

There are two important changes to note in this release:

1. The healthcheck step has been removed. Instead we deploy to all servers. However we hold starting containers on non primary roles until at least one container has started successfully on a primary role.
2. By default, we will build the app from a local git clone of the repo instead of a git archive. Like with a git archive this ensures a clean reproducible build, but it also respects the .dockerignore (which git archive builds do not). If you want to build directly from the check out, you can set the build context to ".".
