Removing text from doc/command-line.md to fix the sourmash signature split docs

[keyabarve]

• The sourmash signature split docs incorrectly state that it is the only command that supports loading signatures from LCA and SBTs.
  The following text has been removed from doc/command-line.md in the sourmash repo:

Note: unlike the rest of the sourmash sig commands, split can load signatures from LCA and SBT databases as well.

Please review. @ctb @luizirber

hi @keyabarve it looks like you started from the branch you used here - #1423. If you look at the diff, you'll see all of those changes are part of this PR, too, and were even before I merged them into latest.

To avoid this, when you make a new branch make sure to do the following:

git checkout latest
git pull origin latest
git checkout -b <new branch>

thanks!

@ctb I realized my mistake. I will keep that in mind from next time.
