doc: redirects: Fix nRF board redirects

Fix the board redirects. The following boards existed before we moved to
a new style of URL for boards, and thus each have 2 entries (old style
old name to old style new name; new style old name to new style
new name):

- nrf51_pca10028
- nrf52810_pca10040
- nrf52840_pca10056
- nrf52840_pca10059
- nrf52_pca10040
- nrf52_pca20020

The following boards did not exist (or were not referenced) before we
moved to the new style of URL for boards, and thus only have one entry
(new style old name to new style new name):

- nrf51_pca10031
- nrf52811_pca10056
- nrf52833_pca10100
- nrf52840_pca10090
- nrf5340_dk_nrf5340
- nrf9160_pca10090
