Allow passing accordion title/content via slots

[bgilhome-now]

Describe the feature

To be able to easily render a component (e.g. a RplDataTable) within a RplAccordion item, by using a slot for accordion content.

Motivation

Currently the accordion takes an items array of objects to define item id, title & content (HTML passed as string). This makes it difficult to setup complex HTML or render Vue components in accordion content.

Proposal

Use a slot (default slot) to capture accordion content. The slot content's children will be used as the content for the separate items entries. i.e. slot children length must equal items length.

Titles could optionally be passed the same way, via a named slot title. The items prop could even be optional, using an auto-assigned integer index (1-based) as item.id if not set.

Benefits

Ease of rendering accordions with complex content.

Drawbacks

Maybe confusion as to the slot children aspect (i.e. slot has 5 tags => 5 accordion items)? Might dynamically named slots e.g. <slot name="content[0]"> be better, or more confusing?

Adoption strategy

Update documentation. No breaking changes, accordion can be used as current.

Agree with this entirely @bgilhome-now - It was missed when it was originally implemented. I'll see what we can do to get this in the backlog
