Prevent height change in Collapse component title

[figureone]

When toggling show/hide, if the title has a different background color than the content, and if there is lengthy content, you can see the title row/track grow during the animation before returning to its original size. Using max-content instead of auto in the grid-template-rows rules should lock the height of the title, so only the 2nd row (content) changes from 0fr to 1fr.

Thanks for considering, love the component library!
