Documentation: Fix broken tables

- The 4.19 release notes included a list of outstanding issues formatted
  as a markdown table, which is not supported by Recommonmark. Reformat
  as an embedded reStructuredText table.

- The table of boards supported on the 4.18 branch did not include row
  separators causing all rows to be rendered in a single row of cells.

- Technotes/console.md had a typo in the rST table formatting which
  generated warnings in the Sphinx build, causing the table to not be
  rendered in the resulting html.
