REST Messaging Configuration Shouldn't use CLI

[Mrc0113]

Update REST Messaging Tutorials to use PubSub+ Manager instead of CLI as CLI is no longer allowed by default in Solace Cloud.

For example, this tutorial: https://github.com/SolaceDev/solace-dev-tutorials/blob/master/src/pages/tutorials/rest-messaging/publish-subscribe.md

Raised by the docs team:

From Doc;1536 (Jira).
We receive a feature request to update the documentation for Solace dev example tutorials, e.g. https://tutorials.solace.dev/jms/using-jndi/.
The request is to provide PS+ Manager UI based configuration or REST configuration where there are CLI based configurations. The reason is that users on Solace cloud do not have access to CLI. The CLI commands in the examples can't be used by those users. They need to perform those configurations using PS+ Manager or REST. The example documentation should be updated for those users.
