[API Creation] API Creations with version having context fails.

### Description

As per the requirement in Hybrid GW integration to Bijira,
Choreo Product APIM generates API context as 

```
^\/[A-Za-z0-9_-]+\/[0-9]+\.[0-9]+\.[0-9]+$
```

Ex: `/location/1.0.0`

But sending this to the platform API gives HTTP 400 saying 
```
{"code":400,"message":"Bad Request","description":"Invalid API context format"}
```
