Replace segmented-control with segmented-control-button-group

• Step 1 - Replace segmented-control with segmented-control-button-group
• Step 2 - Use SegmentedControlButtonGroup in policy editor

Description

Based on &7261, we want to reprecate segmented_control.vue. In this MR we introduce a new component segmented_control_button_group which has the same interface, but the desired implementation.

We use this new component to address #348103 (closed) by replacing the segmented_control.vue reference.

We'll follow up with a push to move this to GitLab UI

Screenshots

Still works 🎉
