Clarifying the service ls filter on name only uses the prefix

[sudo-bmitch]

- What I did

Doc clarification since a name filter will not match on a service name's suffix.

- How I did it

Edit to the markdown. No code changes.

- How to verify it

Create any service and attempt to filter on the suffix rather than prefix of the service name. This does not work so the docs should be updated to match the behavior.

- Description for the changelog

See the following references to users confused by this behavior:
