dynamically pin asyncssh and python versions
- version-pinning asyncssh dependency as defined in the upstream heralding requirements file (current sed command is accidentally concatenating the hard-coded string "1.18.0" with the version defined in the upstream heralding requirements file, resulting in a string like "asyncssh==1.18.0>=2.0.0". This will cause the Docker build to fail.
- dynamically setting python installation directory, making this Dockerfile compatible with any version of python (current path is hard-coded and the build might fail if a newer version of python - e.g. 3.8.1-r1 is installed)
