nft.8: Clarify 'index' option of add rule command

Documentation for add rule command might trick readers into believing
the optional 'index' argument does not need to be that of an existing
rule. This false assumption is fueled by the fact that iptables allows
to insert with last rule number + 1 to actually append to a chain.
Change the relevant sentence to clarify that.

While being at it, drop the deprecated 'position' option from
documentation - since this will likely go away at some point, don't
encourage users to use it although they should notice that they
shoudn't.
