3cef8c27 - Announce expanded/collapsed state on the timeline group header (#7226)

Announce expanded/collapsed state on the timeline group header (#7226) * Announce expanded/collapsed state on the timeline group header GroupHeaderView (the accordion-style header used for grouped state events in the timeline) uses toggleable() combined with clearAndSetSemantics { contentDescription = text }. The clearAndSetSemantics block discards the state information that toggleable() would otherwise expose, so TalkBack never announces whether the group is currently expanded or collapsed. Add an explicit stateDescription (two new a11y_state_expanded / a11y_state_collapsed strings in temporary.xml) alongside the existing contentDescription so the expanded/collapsed state is communicated to assistive technology. Internal note: this single-file/single-root-cause fix addresses three separate BITV findings raised in the same accessibility audit against this component's toggle semantics. * Update screenshots --------- Co-authored-by: ElementBot <android@element.io>
