therubyracer doesn't appear to be under active development
I didn't need this for PRs that I was doing, but a `bundle install`
failed because of it. I know I can specify the groups as a workaround
but replacing this seems like it might reduce a small barrier to
contributing
Move rswag-specs under development and test to resolve this warning:
```
Your Gemfile lists the gem rswag-specs (>= 0) more than once.
You should probably keep only one of them.
Remove any duplicate entries and specify the gem only once.
While it's not a problem now, it could cause errors if you change the version of one of them later.
```
Adds to swagger_Formatter to remove injected body parameters since those are 2.0 and ont 3.0 compliant
Adds to example_group_helpers to only automatically save request examples in the swagger output on 2xx response, since otherwise it was getting clobbered
I have added database cleaner as for formatter spec it was trying to
use inbuild transactional fixture flag, which was failing as it
couldn't find any transaction to rollback. Hence switched to using
database_cleaner gem for using truncation as strategy
