Subject: [PATCH] IsTank fix for Death Knight (#2296)

<!--
Thank you for contributing to mod-playerbots, please make sure that
you...
1. Submit your PR to the test-staging branch, not master.
2. Read the guidelines below before submitting.
3. Don't delete parts of this template.

DESIGN PHILOSOPHY: We prioritize STABILITY, PERFORMANCE, AND
PREDICTABILITY over behavioral realism.

Every action and decision executes PER BOT AND PER TRIGGER. Small
increases in logic complexity scale
poorly across thousands of bots and negatively affect all. We prioritize
a stable system over a smarter
one. Bots don't need to behave perfectly; believable behavior is the
goal, not human simulation.
Default behavior must be cheap in processing; expensive behavior must be
opt-in.

Before submitting, make sure your changes aligns with these principles.

TRANSLATIONS:
Anything new that the bots say in chat must be in a translatable format.
This is done using GetBotTextOrDefault,
which you can search for in the codebase to find examples. Your code
needs to have English as the default fallback,
while the full translations need to be in an SQL update file. The
languages in the file are the nine language
options supported by AzerothCore: English, Korean, French, German,
Chinese, Taiwanese, Spanish, Spanish Mexico, and
Russian. See
data/sql/playerbots/updates/2025_12_27_ai_playerbot_fishing_text.sql as
an example of a translation SQL
update, whose content are called within the codebase at
src/strategy/actions/FishingAction.cpp
