Rename src folders and fix error in CD Pipelines

[kottofy]

This PR:

• renames all src folders from example src/nyc_src to src/nyc_taxi
• Adds a continue on error for the cd workflow when copying the src/{{model}}/common folder which doesn't exist in all models. Without this, the pipeline fails

Resolves issue #192

do we know if the azdo continue-on-error still produces a warning/error log? if not, it may be useful to log it via the below bash command:

 if [ -d "src/${{ inputs.model_type }}/common/" ]; then
              cp -r src/${{ inputs.model_type }}/common/* model/${{ inputs.model_type }}/online
            else
              echo "Warning: Directory src/${{ inputs.model_type }}/common/ does not exist" >&2
            fi

Left 1 comment around ensuring that a log message is produced when the YML job for "copying common files" fails. LGTM!
