Should we do a version check instead (== "0.1.0") for the legacy decoding rather than falling back to it if the variants key is missing, or do you think it's not worth it?

That would require that we encode the version information in the JSON, which we would probably do once for the entire file instead of once for per element.

Now, the data continues to be encoded directly in the summary and each variant only sets the information that's different in that source language.

I made some changes to the spec and the implementation to reduce the amount of duplicate encoded data when some content is the same in multiple languages. This also makes the single source language content almost the same as previously (the only difference is that Since the changes are so small we could decide to redundantly encode the |

Should we use .none here maybe? To differentiate between the wrapper and the inner value a little more.

Nit: Note's render kind of strangely if they're not embedded in other content. It might be better to just make this a regular discussion.

Summary
This updates
LinkDestinationSummaryand the LinkableEntities.json spec to support multi-language content by moving the properties that can vary into aContentVariantsubstructure.The implementation supports decoding data in the "0.1.0" format but the encoded data will always be in the "0.2.0" format.
Dependencies
As a code change this doesn't depend on #47 but the changes in this PR are not useful without the base support for multi-language documentation catalogs.
Testing
Convert a multi-language documentation catalog and include the
--emit-digestflag so that Swift-DocC will create the linkable-entities.json file.(For testing purposes it may be convenient to also set the
DOCC_JSON_PRETTYPRINTenvironment toYESto get output that's more easily inspectable.)The content of the linkable-entities.json file should include the variant content of each interface language for each "entity".
