Instead of hard-coding the version into build.gradle, this change derives the version from git tags.

If the HEAD commit has a tag in the format "`vM.N`", the version number `M.N` is used directly. Otherwise, a snapshot version is assumed, and the version becomes `M.(N+1)-SNAPSHOT`.

This fix PECS rule (producer extends, consumer super) to the Hamcrest IsIterableContaining matcher, as well as dependant implementations. In this instance, a collection of items should be treated as a producer according to this rule, while a matcher acts as a consumer.

There is also an extra test for type variance in hasEntry (hamcrest#107)

Closes hamcrest#252

This change migrates all tests to use JUnit Jupiter, so that is all tests are now annotated with `org.junit.jupiter.api.Test`.

In most cases, this is a simple change of imports, with a few exceptions:
* Uses of `assertTrue` have been adjusted to allow for the description being the last parameter
* `org.hamcrest.AbstractMatcherTest` has been moved to `org.hamcrest.test.AbstractMatcherTest`
* Static assertion methods in `AbstractMatcherTest` have been moved to `org.hamcrest.test.MatcherAssertions`
