feat: provide gpg identity signature check

[smira]

Breaking change: .conform.yaml gpg: bool field was changed to be a structure:

gpg:
  required: true
  identity:
    gitHubOrganization: talos-systems

(identity is not required)

This enforces that GPG signature should come from one the members of the GitHub organization to succeed, i.e. commit is signed by the member of the organization.
