chore: reset release-please config (#987)

setting next sdk-rtl version to 21.3.3 because package.json and all the
dependencies currently point to 21.3.2 but release-please missed it so
next time it runs it thinks it will be starting at 21.3.1 which is what
is recorded in the last release at f886733
