chore: switch to @tony.ganchev/eslint-plugin-header

[tonyganchev]

Description

Hi, team,

I noticed you are using eslint-plugin-header on ESLint 8.

I forked @tony.ganchev/eslint-plugin-header mid-2024 to add support
for ESLint 9 and hoped it would be a temporary measure but since the
original has not been updated for five years I decided to continue
improving the new plugin and have been doing so for the last two years.

Specific improvements include:

• full JSON schema for validating the configuration.
• fixed multiple bugs with the behavior of the plugin on Windows.
• many other bug-fixes.
• improved autofixing and error-reporting behavior.
• added support for leading pragma comments before the header such as
  @jest-environment and eslint-env. In the case of the current
  review, this allowed me to remove the eslint-disable directive from
  a file and reintroduce validation.

I switched the configuration to use the new config format for v3.2.x
as the leading comments feature is not supported by the array-based
format inherited from eslint-plugin-header.

I've sent PR proposals to other projects in the cloudscape-design
space:
