fix: address latest norminette v3.3.55 update incompatibility issue

[ygor-sena]

The latest norminette v3.3.55 doesn't allow students to choose between the K&R or Allman indentation style; instead, it enforces the use of the latter. The K&R indentation style is used in the original Unix kernel, while the Allman style is used in BSD Unix.

Deciding whether to pin the tools used on CD/CI or to keep them updated is a complex question. We must consider factors such as stability versus being up-to-date, security, long-term maintenance, and compatibility. Therefore, I opted for a balanced approach, pinning the Norminette version to v3.3.51, which was the latest version at the time this project was developed and its only major tool.

Since the project is finished, it doesn't require long-term maintenance, nor will it have major security issues since the tool used is only a code formatter. Therefore, I addressed the issue of compatibility as our whole project is structured to adhere to norminette v3.3.51.

However, while I was at it, I decided to make some minor changes to the code to conform to the new norm and only left the critical ones. The norminette v3.3.55 is stricter than the old one regarding preprocessor definitions. The log below references the file include/hash_table.h:

# define RIP ((void *)1)

Error: PREPROC_CONSTANT     (line:  19, col:  14):      Preprocessor statement must only contain constant defines

To sum up, this PR ensures that our CI/CD doesn't break due to external changes if we further tinker with this hard and amusing project.
