fix(config.ts): fix config priority

[hydrotho]

Problem Description

In this project, according to the README documentation, local configuration should have a higher priority over the global configuration. However, in practice, it was observed that the local config wasn't overriding the global config as expected. Upon investigation, I identified that the issue originated from a logical error in the getConfig() function in the src/commands/config.ts file.

Changes

To address this issue, I have made necessary modifications to the getConfig() function. These changes ensure that the local config correctly overrides the global config.

Testing and Validation

To validate the effectiveness of this fix, I conducted a series of tests including various combinations of global and local configurations. These tests have confirmed that the modified code now aligns with the expected behavior as described in our README.

Checked the current master: environment configuration already explicitly takes precedence over ~/.opencommit through mergeConfigs(envConfig, globalConfig), including false and null, and unit tests cover it. This PR conflicts and no longer provides a needed change. I recommend closing it as superseded.
