OSDOCS-5355: correct command for creating kustomization.yaml

The command uses bash "here document" syntax to create a file, but the
content of the file was in a separate text box and so could not be
selected all at one time. This patch combines the command for creating
the file with the contents of the file and removes a syntax error
from the middle of the content.
