Add support for Block field in Closed summary

Yeah, as block field is pretty common, we could add support.
Hopefully we will find a better approach for a generic summary approach.
Pity we can't rely on some generic builtin summary / label functionality.

That said, the magic word to pass the wall is "tests" :-)

Let's write some tests.

Added tests.

Added a test dependency to Block Field.

Added a composer.json file with test dependencies to Paragraphs.

Added regular dependencies to the composer.json file.

I don't see why the field name check here is necessary, a block_field is never going to be named like that.

Also, a comment to explain what this does would be good.

Thanks, don't forget to provide an interdiff when updating a patch.

Needs a . at the end of the comment, looks fine otherwise.

Committed. :-)
