docker readme.md: Remove VISSR vss_vissv2.binary and vsspathlist notes

Update the docker readme.md to reflect changes brought about by CDSP now
using VISSR v3:

1. VISSR now provides a default binary list of VSS nodes so remove the
   note about having to generate vss_vissv2.binary
2. VISSR no longer serves a list of the VSS nodes supported at the URL
   http://<server ip>:8081/vsspathlist. Remove the associated note.

-Tip: The playground maintainers have found that the method involving running `make binary` in a git clone of the VSS source tree to generate the file is straight forward. Note: check the VSS readme for the python requirements for the tooling.

 If you are working behind a corporate security system that places a _man-in-the-middle_ between your host and the internet you may see security errors when artifacts are downloaded as part of the build process.
