No longer need this boolean re-cast; ES indexes return proper bools now.

As per discussion in metacpan/metacpan-web#2438, the ElasticSearch
indices that back the MetaCPAN API have been updated to now consistently
return Boolean values for the `deprecated` field.

Thus, no longer need this check for string `"true"` or `"false"` values,
which would then be cast accordingly to a proper boolean.
