Use grid instead of equalizer in recommendations

It's August 2025 and support for grid layout has been available in about
99% of the browsers for some time now. All major browsers added support
for grid layouts in 2017, which means our rule to support browsers that
are 7 years old allows us to start using `display: grid`.

Using a grid layout allows displaying a dynamic number of rows while
keepin all of them the same height, the same foundation's equalizer
does, by setting `grid-auto-rows: 1fr`.

And the `grid-template-columns` property lets us use dynamic columns for
all screen sizes, always filling the available space. No need to use
breakpoints.
