Change contextual docs to reflect three changes to `given` syntax: - put `given` inside the parentheses of parameters and arguments, as was suggested by @smarter. - change given import syntax to make `given` an import selector - change `the` to `theGiven`.

Allowed anywhere a pattern is allowed. This is useful in for expressions, i.e.
It is also a necessary ingredient if we want to express implicit matches as a library method, which
