Mislabeling of weapon skills

Examples of Dagger 3 and Greatsword 5 on a [Harbinger page](https://hardstuck.gg/gw2/builds/necromancer/power-quickness-harbinger/)


Greatsword 5 is labeled correctly on a [Reaper page](https://hardstuck.gg/gw2/builds/necromancer/power-reaper/) but Dagger 3 does not.


Dagger 3 is not labeled correctly even on [Core Necromancer](https://hardstuck.gg/gw2/builds/necromancer/core-necromancer-2/)

Code to review, may be caused by the specialization check, breaking with weapon mastery, it doesn't explain the mislabeling of dagger though. https://github.com/HardstuckGuild/GW2-Tooltips.js/blob/master/src/TooltipsV2.ts#L899

Start at src/TooltipsV2.ts around line 899 and compare the weapon-skill labeling on the Harbinger, Reaper, and Core Necromancer pages linked in the issue. Check whether the specialization check interacts with weapon mastery and whether it explains both Dagger 3 and Greatsword 5. Done means the affected skills are labeled correctly across those pages.
