Duplicate object IDs when running WrapTableAndMathInAContainerTransform

[stefan6419846]

Tables and math sections processed by the theme generate duplicate tag IDs, which violates the uniqueness requirements of IDs.

Generated section (example):

<div class="table-wrapper docutils container" id="index-0">
<table class="docutils align-default" id="index-0">
<thead>

This is due to

furo/src/furo/__init__.py

Lines 55 to 58 in 522d7e6

	new_node = nodes.container(classes=["table-wrapper"])
	new_node.update_all_atts(table_node)
	table_node.parent.replace(table_node, new_node)
	new_node.append(table_node)

copying all attributes (including the IDs) from the original node without further modification.
