Minor typo in docs/en/ingest-management/elastic-agent/example-kubernetes-standalone-agent-helm.asciidoc

[jamie-wilson88]

Hi!

docs/en/ingest-management/elastic-agent/example-kubernetes-standalone-agent-helm.asciidoc

has this typo:

 Open a terminal shell and change into a directory in your local clone of the `elastic-agent` repo.
. llowCopy this command.

Probably should just say "Copy this command"

Thanks!
