Update texts and add help texts

[nkylstad]

Description

The policy editor is difficult to understand, as it builds on the policy XACML, which uses a lot of very specific and confusing terminology.
There are several things we can do to address this, but this issue aims at making some changes to the texts that are used in the editor, as well as adding some new texts (help texts or descriptions) to make it easier to start working with the policy.
This will come in addition to documentation for the editor, but hopefully will also reduce the need to use the documentation actively.

Here is my suggestion of places we could add more info. Once the documentation is ready, we can also add a link to the documentation.

In most cases, we should consider just adding a help text, using the HelpText component from the design system.
