Session Replay: Expand collapsed breadcrumb

When breadcrumbs have `data`, the SDK shows a single line with a count of items, which is expanded when clicked:


The problem is that the data is all that's relevant to these breadcrumbs.
And there's a lot of horizontal space.

Suggestion:

Expand the data horizontally, and add `...` if max length is reached.
The click to expand behavior can stay, and the json can be indented when clicked.

Start by locating the Session Replay breadcrumb renderer and its collapsed data view, then inspect how click-to-expand currently works. The change is done when breadcrumb data uses available horizontal space, adds an ellipsis at the maximum length, preserves click expansion, and shows indented JSON when expanded.
