API playground target annotation query crashing in production due to obsoleted endpoint

[d0choa]

The target annotation example query from the Platform API playground crashes. I have identified the reasons (typos in the query):

Crashing query

``` query targetAnnotation { target(ensemblId: "ENSG00000169083") { id approvedSymbol tractability { modality id value } safetyLiabilities { event eventId biosample { cellFormat cellLabel tissueLabel tissueId } effects { dosing direction } study { name type description } datasource literature } } } ```

Working query

``` query targetAnnotation { target(ensemblId: "ENSG00000169083") { id approvedSymbol tractability { modality id value } safetyLiabilities { event eventId biosamples { cellFormat cellLabel tissueLabel tissueId } effects { dosing direction } studies { name type description } datasource literature } } } ```

@chinmehta could you please replace the "crashing query" with the "working query" in the API Platform playground?

It might be a good excuse to update all the example queries with the latest endpoints.

The disease annotation is also not working for the default selected disease as it does not have clinical signs and symptoms.

Solution: Replace the disease in the input query: EFO_0000222

Query that works

```query diseaseAnnotation { disease(efoId: "EFO_0000222") { id name phenotypes { rows { phenotypeHPO { id name description namespace } phenotypeEFO { id name } evidence { aspect bioCuration diseaseFromSourceId diseaseFromSource evidenceType frequency frequencyHPO { name id } qualifierNot onset { name id } modifiers { name id } references sex resource } } } } } ```
