Dash in villager/trader UI is hardcoded / untranslatable

The Bug

The dash / separator between the villager's profession and level is untranslatable in the trade GUI.

Among other things, this means resource packs are unable to alter this part of the interface. This is particularly jarring with packs that recolour text.

Expected Result

The dash / separator would be translatable.

Note:

Even better: "<profession> - <career level>" should be translatable (%s - %s), so that languages can change the word order and spacing if needed

Code analysis (tentative)

...
private static final Component LEVEL_SEPARATOR = new TextComponent(" - ");
...
protected void renderLabels(PoseStack poseStack, int a, int b) {
        int traderLevel = ((MerchantMenu)this.menu).getTraderLevel();
        if (traderLevel > 0 && traderLevel <= 5 && ((MerchantMenu)this.menu).showProgressBar()) {
            MutableComponent traderLabel = this.title.copy().append(LEVEL_SEPARATOR).append(new TranslatableComponent("merchant.level." + traderLevel));
            ...
        }
    ...
    }
...

LEVEL_SEPARATOR should be a TranslatableComponent instead of a hardcoded TextComponent.
