Add the possibility to pass a list of trusted packages that can be ignored with Trusty rule type

[samuv]

Hi!

During this issue, I noticed that there's currently no way to ignore the evaluation of specific packages within the pr_trusty_check configuration.

It might be useful to add an option to define a list of known or accepted risks, allowing users to skip repeated warnings for certain packages. This could help reduce noise and make the review process more efficient.
