Correct the error message with respect to runner configuration

Consider an example where a user has configured a runner type "Docker Linux(x86_64)", but has defined a "linux shell" type in the YAML configuration

 runs-on:
                - 'self.hosted'
                - 'linux.shell' # correct config should be 'linux'

Error observed when user try to run the pipeline:

"The Docker feature is not supported on this self-hosted runner's platform."

The above error is misleading, and does not help the user to get the root cause of the issue. The request, in this case, is to update the error as

"could not find any runner with label linux.shell"

or

Runner type specified is incorrect
