[PATCH] config/advice.txt: fix description list separator

The whole submoduleAlternateErrorStrategyDie item is interpreted as
being part of the supporting content of the preceding item. This is
because we don't give a double-colon "::" for the separator, but just a
single colon, ":". Let's fix that.

There are a few other matches for [^:]:\s*$ in Documentation/config, but
I didn't spot any similar bugs among them.

 This was the only thing that stood out at me while going through
 `./doc-diff v2.24.0 origin/master`. This is obviously a non-critical,
 purely cosmetic issue.
