[TBC bracket, PVP] - Re-introduction of Uniqueness vs. unification of Crit value for Gems

CC Issue: https://github.com/chromiecraft/chromiecraft/issues/5717

### What client do you play on?

enUS

### Faction

Both

### Content Phase:

70

### Current Behaviour

The Epic PvP Gems are going to become accessible with the re-added limitation of them being unique.
Back in TBC 2 separate gems existed for melee crit chance and spell crit chance.

In wotlk, these stats are merged into 1 crit value affecting both melee and spell crit.

Given that the uniqueness of these gems has been re-introduced, primarily to prevent early, unlimited access to attackpower and spellpower gems, we will have access to 2 crit gems instead of 1 per damage type.

### Expected Blizzlike Behaviour

To properly progress through the availability and given content in tbc but on a wrath client

A) the gems should be reverted to affect melee or spell crit respectively only
B) (likely easier) make 1 of 2 gems not available

Start by comparing the TBC and Wrath Wowhead results linked in the issue, then inspect how the progression module defines the listed Epic PvP gems and their uniqueness. Done means applying one decided behavior—separate melee and spell crit effects, or removing one gem—and verifying the available gems match the intended TBC progression.
