Fix confusing section in docs/README

It looked like it was telling you to add both `// TEST[continued]`
and `// TESTRESPONSE` to the same snippet which doesn't do anything.
Instead it was trying to say that you can have many snippets included
into the same test by doing:

```
request1
```
// CONSOLE

```
response1
```
// TESTRESPONSE

``
request2
```
// CONSOLE
// TEST[continued]

```
response2
```
// TESTRESPONSE
