Deleted the offline_checkDependencies function and unified logic in offline_checkPrerequisites function

[CarlosALgit]

Related issue

Closes #96

Description

The aim of this PR is to unify the offline_checkDependencies and offline_checkPrerequisites functions due to they were using almost the same logic.

To unify them, we had to change how the dependencies array is treated inside the function and differentiating when the function is used to check the Wazuh Installation Assistant dependencies or the Wazuh Offline dependencies.

Tests

We have performed an Offline installation using the Assistant in both rpm and deb package managers:

Note

There are some logs in the test that shows which dependencies are being taken in the function. This logs won't be in the final version, they're just on a trial basis.
