what:
Introduces 2 new features to promotion module:
1. Introduce max quantity limit to promotion application - This will limit the application of the promotion based on the quantity of the target products in the cart.
2. When applying buy get promotions, we will now apply buyget promotion until eligible items are exhausted or max quantity is reached.
```
- Buy 2 t-shirts, Get 1 sweater
- Max quantity -> 1
This means you can add two t-shirts, and get 1 sweaters for free. However, if you add four t-shirts, you only get one sweater for free.
```
```
- Buy 2 t-shirts, Get 1 sweater
- Max quantity -> 3
This means you can add six t-shirts, and get three sweaters for free. However, if you add eight t-shirts, you only get three sweaters for free
```
```
- Buy 4 t-shirts, Get 2 sweater
- Max quantity -> 1
This should throw on creation, as the max quantity should as a minimum be the same value as the target rule quantity
```
RESOLVES SUP-2357 / https://github.com/medusajs/medusa/issues/13265
* This fixes the discount_ calculation logic
* This fixes the adjustment to be handled as a subtotal value in every calculation and applies the tax inclusive logic on the promotion value itself
* Added some testcases and revoked some changes to improve testing output
* Fixed a test case based on feedback
* Corrected promotion/admin test cases
* Corrected cart/store test case
* Improved cart/store test cases for more robust promotion testing considering tax inclusion flags
* Remove unnessary changes as adjustments now automatically are subtotals and therefore the tax inclusive flag does not need to be applied again
* Remove adjustments->is_tax_inclusive usage everywhere
* Migration script to remove is_tax_inclusive in cart line item adjustment
* Forgot to adjust one more testcase
* Corrections based on fPolic feedback
* Refactored PR to consider feedback from oliver
