[skip-changelog] Eliminate empty lines produced by `board details -b` (#1997)

* Eliminate blank line between required tools row entries

* Fix Programmers ID typo and modify tests accordingly

* Reduce spacing between "Required tool" columns

Splitting the table produced by `board details` after `Platform checksum` resets both the average length and the variance of the following cells, thus reducing the space between entries.
