V3 Fix: Ignore sub packages regex is not adhered

[Orbsynated]

Description

The current implementation checks the ignored sub packages regex on the packages that are configured in the config file(when recursive: True), but not on their sub-packages.

Type of change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• This change requires a documentation update

Version of Go used when building/testing:

• 1.22
• 1.23

How Has This Been Tested?

1. I created a .mockery.yaml file and ran it against a package which has sub-packages(using recursive: True option).
2. I added a regex(using exclude-subpkg-regex to ignore those sub-packages).
3. Before my fix the sub-packages which were excluded were still being ran on. After which, they were not.
