README: trim stale -parameters block (drop version 3.6.0 hedge and +10K delta)

Was three lines describing the -parameters compiler flag as a recent
change "as of version 3.6.0" with a parenthetical noting it added ~10K
to the jar. Current is 4.102.0; the version reference is stale and the
size delta is no longer interesting against the stable baseline.

Kept the substantive fact in one line — readers who care about
reflection-based parameter retention still see the signal; everyone else
sees a tidier intro.
