Update dockervolumes.md - Changed all wrong /opt/webapp 

Changed all wrong /opt/webapp as /webapp

/opt/webapp of web container includes app.py, if set destination folder as /opt/webapp, app.py is not visible and below error log presents and the web container will exit, so it's better to set the destination folder as /webapp.

docker logs -f web
python: can't open file 'app.py': [Errno 2] No such file or directory

This command mounts the host directory, `/src/webapp`, into the container at
`/opt/webapp`. If the path `/opt/webapp` already exists inside the container's
`/webapp`. If the path `/webapp` already exists inside the container's
image, the `/src/webapp` mount overlays but does not remove the pre-existing
content. Once the mount is removed, the content is accessible again. This is
consistent with the expected behavior of the `mount` command.
