Tables may need additional padding

Compare the way the code block interacts with other elements vs. the table. The content below the table here:

Seems awkwardly close to the table.

I am not sure if tables should have `padding: 10px` similar to `.media-content pre`, or unequal padding/margins similar to `p`. We should look at our usages of tables alongside paragraphs and code blocks and make sure whatever we do doesn't result in awkwardly large gaps.

The screenshot is from https://bevyengine.org/learn/migration-guides/0-13-to-0-14/ with #1398.

Start at the migration guide page linked in the issue and compare the table with nearby code blocks and paragraphs, then inspect the website styling and other table usages. Done means the table content has intentional, consistent spacing without creating oversized gaps across the reviewed examples.
