Auto merge of #115055 - Kriskras99:master, r=ehuss

Fix table issues in platform support documentation (closes #115047)

mdBook needs an empty line before and after the table block.
In addition, in the tier-3 list three targets forgot about the host column and therefore showed the notes in the host column.

Closes #115047
