Table - add docs for using with container queries

A short version of it is in core here - https://www.patternfly.org/components/table/html#responsive-layout-modifier-usage

IMO I'd like to at least update the wording so that "container queries" or "container query" are on the page somewhere in case someone searches for it. From the core docs, instead of this

Note: If a wrapping element creates an inline-size or size container with the container name pf-v6-contain-table, the breakpoints will apply to the container's width.

I'd advocate we add another h3 under the grid classes table with "Container queries" and some text like

To base the table's responsive classes on a container's width rather than the viewport, apply a CSS container named pf-v6-contain-table to the target ancestor element. For example:

.my-table-wrapper {
  container: pf-v6-contain-table / inline-size;
}

阅读现有的 Table 文档，并将其与 issue 中链接的 core Table responsive-layout modifier 用法进行比较。找到 grid classes 部分，添加可搜索的 container-query 指南和 CSS 示例 pf-v6-contain-table，然后验证渲染后的页面包含新的标题和说明。
