Redis 7.2 undefined symbol: RedisModule_TryCalloc + my fix
If I use this repository as so :
export RM_INCLUDE_DIR=$(pwd)/7.0
make clean
make
make run
I get the following output/error :

But, If I download the redismodule.h file from the redis repo 7.2 branch, everything works fine, solving my problem.

I'd give you a PR but:
- I don't fully understand your intent/release matching pattern
- I'm very basic in the c space.
Best of luck
