Add the comment inline suggestion to the transaction.search conduit endpoint

[SpangleLabs]

It was mentioned that this doesn't exist in this API endpoint at the moment. It would be very helpful, so let's add it!

Here's the method to fetch the inline suggestion:
https://github.com/thought-machine/phorge/blob/tm-master/src/infrastructure/diff/inline/PhabricatorDiffInlineCommentContentState.php#L28

And here's the method to get that comment state:
https://github.com/thought-machine/phorge/blob/tm-master/src/infrastructure/diff/interface/PhabricatorInlineComment.php#L362

I'm not able to test locally, but we can test this on our dev environment after landing (or before if we want to deploy from a fork)

We may need to check first if comment is an instance of PhabricatorInlineCommentInterface, instantiate a newInlineCommentObject(), on which we can then call getContentState() and do if getContentHasSuggestion()... ; i'd need to test this locally and see what the api returns for other objects with comments (it may complain about missing getContentState(), but I may be wrong)

I'm rusty on this, so take it with 2 pinches of salt: not all PhabricatorApplicationTransactionComments may implement getContentState()

~/src/phorge$ cat src/applications/differential/storage/DifferentialTransactionComment.php | grep -B 1 -A 2   getContentState
    return $this->newInlineCommentObject()
      ->getContentState()
      ->isEmptyContentState();
  }

(I suspect comments are rows from the db,

~/src/phorge$ cat src/applications/transactions/storage/PhabricatorApplicationTransactionComment.php | grep -A4 PhabricatorApplicationTransactionComment
abstract class PhabricatorApplicationTransactionComment
 extends PhabricatorLiskDAO
 implements
<..>
```)

Ah yeah, might not be right with the PhabricatorInlineComment type here, especially if we're looking at a non-differential object, hmm

There we go, updated it
