Update ordinal.ts to match Python version (#799)

* Update ordinal.ts to match Python version

From the Python docs: While there is no one-to-one correspondence between Elo and OpenSkill, one standard deviation is approximately equivalent to around 200 points for an Elo rating starting at around 1500. To mimic Elo, simply set alpha to 200/sigma and target to 1500 for ordinal().

* Update ordinal.test.ts to reflect new alpha and target params

* fix: leverage constants setup to ensure backward compat
