Update hidden_explanation to include labels

[NoRi2909]

Currently the explanation for switching off "Visible" for entities is as follows:

The first part of the explanation is misleading as it says "… will not be shown on your dashboard …".

1. There are multiple dashboards today, so there is not a single one like this is implying.
2. You can still place any hidden entity on your dashboards.
3. So this refers to the auto-populated"Default dashboard" type, only.

Proposed change

The most important result of hiding an entity is that it is no longer included when its area, device or label is referenced.

This PR adds labels to the explanation and drops the (obvious) part about the auto-populated dashboard that is misleading regarding all custom dashboards.

Not sure if entirely removing the dashboard mention is ok but clarifying it is not easy either

[NoRi2909]

Yes, a difficult decision. But as soon as you mention the word "dashboard" again you need to add quite some explanation that they do in fact not disappear from any user-created dashboard.

The auto-populated dashboard is for absolute novices, and they will either not touch that setting at all or when they turn off the "Visible" switch they will kind of expect them to be not included in the automatic dashboard.
