Berserker Rage support (#2261)

<!--
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.

## Pull Request Description
<!-- Describe what this change does and why it is needed -->

Added Berserker Rage usage (in combat and outside combat) for Warrior
(all specs)

Related with: #1755 

## How to Test the Changes
<!--
- Step-by-step instructions to test the change.
- Any required setup (e.g. multiple players, number of bots, specific
configuration).
- Expected behavior and how to verify it.
-->

- invite warrior to party
- [optional] start combat (for example with dummy)
- use command `.aura 6215`
- bot should cast Berserker Rage

## Impact Assessment
<!-- As a generic test, before and after measure of pmon (playerbot pmon
tick) can help you here. -->
- Does this change increase per-bot/per-tick processing or risk scaling
poorly with thousands of bots?
    - - [x] No, not at all
    - - [ ] Minimal impact (**explain below**)
    - - [ ] Moderate impact (**explain below**)



- Does this change modify default bot behavior?
    - - [ ] No
    - - [x] Yes (**explain why**)

Warriors use Berserker Rage when they got fear, sleep or sap

- Does this change add new decision branches or increase maintenance
complexity?
    - - [x] No
    - - [ ] Yes (**explain below**)



## Messages to Translate
<!--
Bot messages have to be translatable, but you don't need to do the
translations here. You only need to make sure
the message is in a translatable format, and list in the table the
message_key and the default English message.
Search for GetBotTextOrDefault in the codebase for examples.
