Table headers on rows should be top-aligned

Problem/Motivation

Table headers are vertically-aligned at the bottom of their cell, which is correct for column headers but awkward-looking for row headers.

Example: Brief overview, and history of automated upgrading to Drupal 8 (scroll to the "How to find the migration modules and tools" table)

• "Name", "Where is it?" and "What does it do?", at the top of columns, are correctly bottom-aligned.
• "Migrate", "Migrate Drupal", "Migrate Drupal UI"…, at the left of rows, are incorrectly bottom-aligned. They should be top-aligned.

Proposed resolution

Add a new SASS rule to target <th> elements inside rows after the first one:

sass/partials/common/_table.scss :
tr {
[…]
  &:nth-of-type(n+2) th {
    vertical-align: top;
    }
}
