Improve discoverability of `satisfies`

As of today, the documentation thoroughly explains how to use [Soft Assertions](https://assertj.github.io/doc/#assertj-core-soft-assertions), but there is no mention of [`satisfies`](https://www.javadoc.io/doc/org.assertj/assertj-core/latest/org/assertj/core/api/AbstractAssert.html#satisfies(java.util.function.Consumer...)), which can be a less intrusive option for simpler use cases.

We should generalize the section on Soft Assertions, describing the challenge of performing many assertions without stopping the test and demonstrating how `satisfies` and Soft Assertions can help solve it.
