Revert commit 4664677a4e for solarized-dark.reg

* It made zero changes to the scheme except swapping color assignments
of color 00 and color 08 and swapping `ScreenColors` to match.
* Reverting this commit ensures identical color palettes for both dark
and light schemes with the only difference that `ScreenColors` and
`PopupColors` are swapped for each scheme
* Cleans up extra line space and extra line in solarized-light.reg so
both files have matched formatting
