src/Checks.py: fix typo and use match-case instead of if-else

[bariscodefxy]

This pull request includes several changes to the src/Checks.py file to correct a typo and improve argument handling. The most important changes include fixing a misspelled variable and refactoring the argument parsing logic to use a more modern syntax.

Bug Fixes:

• Corrected the typo in the list function by changing pagkage to package. This ensures that the realmd package is correctly referenced and installed if it is not already. (src/Checks.py, src/Checks.pyL12-R17)

Code Improvements:

• Refactored the argument parsing logic in the id_check function to use a match statement instead of multiple if-elif-else statements. This makes the code more readable and modern. (src/Checks.py, src/Checks.pyL28-R34)
