Incorrect license is not detected/fixed

[radeksimko]

It appears the copywrite will not detect or attempt to fix wrong license, for example in hashicorp/terraform:

If I attempt to change provider_source.go in root to contain

// SPDX-License-Identifier: MPL-2.0

$ copywrite headers
Using license identifier: BUSL-1.1
Using copyright holder: HashiCorp, Inc.

Exempting the following search patterns:
**/*.tf
**/testdata/**
**/*.pb.go
**/*_string.go
**/mock*.go
docs/plugin-protocol/**
internal/tfplugin*/**

The following files are missing headers:

$ head -2 provider_source.go
