fetch, pull doc: correct description of '--set-upstream'

From: Philippe Blain <[email protected]>

The '--set-upstream' option to git fetch (which is also accepted by git pull and passed through to the underlying git fetch) allows setting the upstream configuration for the current branch. This was added in 24bc1a1292 (pull, fetch: add --set-upstream option, 2019-08-19).

However, the documentation for that option describes its action as 'If the remote is fetched successfully, pull and add upstream (tracking) reference [...]', which is wrong because this option does not cause neither git fetch nor git pull to pull: git fetch does not pull and git pull always pulls.

Fix the description of that option.
