NEWS: prefer advertising --jit option [ci skip]

Browse source 
In addition to `--enable=jit` and `--enable-jit`, we're going to ship
`--jit` as a short hand of it in Ruby 2.6.0.

That's because both --enable=jit and --enable-jit are super hard to
type everytime on command line, and I want make it easier to use so
that many people use it. First of all, `--enable=jit` is accidentally
added for consistency with `--disable=jit` and it's not added for human.

As it's a short hand, once JIT became enabled by default, the `--jit`
option would be removed after some deprecation warning period and only
`--enable=jit`/`--disable=jit` will survive. That being said, I still
think having `--jit` as a temporary short hand is valuable for the above
reasons.
