Try it out option for unix get file content endpoint fails due to auto encoding /

[jordanCain]

Describe the bug
When selecting the try it out option for the unix get file content endpoint within the Swagger UI the request will fail for any provided path.

To Reproduce
Steps to reproduce the behavior:

1. Go to Swagger UI
2. Click on Unix files get content endpoint
3. Enter a valid path to a file '/u/jcain/file.txt'
4. Execute and see request auto encodes the path parameter slashes '/'

Expected behavior
The Swagger UI should not change the request path parameter

Additional context
There is a limitation with the Swagger UI see - swagger-api/swagger-ui#1637

The /api/v1/unixfiles/{path}/** in Swagger UI is a little misleading. I finally find it should be /api/v1/unixfiles/u/jcain/file.txt, without **.

One example would be helpful nearby the message of "Try it out function will not work ..."
