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;
}

Lisez la documentation existante de Table et comparez-la à l’utilisation du modificateur de mise en page responsive de core Table liée dans l’issue. Repérez la section consacrée aux classes de grille, ajoutez des indications consultables sur les container queries ainsi que l’exemple CSS pf-v6-contain-table, puis vérifiez que la page rendue contient le nouveau titre et l’explication.
