remaining Shang-Chi in DB

[mmougy]

they are 2 card "Shang-Chi" referenced in the database, but they represent the same card from Taskmaster's set.
In https://github.com/mmougy/marvelsdb-json-data repo, there is only one (the encounter one), so i think the "hero" version should remain in the database and should be removed

this is the correct one (because it is an encounter card)

this is the wrong one (it should not be a hero card)
