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

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``. In the case of the current review, this allowed
  me to remove the `eslint-disable` directive from two tests and
  reintroduce validation which was actually failing because of the
  missing empty line after the header.

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:
- cloudscape-design/collection-hooks#136
- cloudscape-design/components#4308
- cloudscape-design/demos#243
- cloudscape-design/test-utils#114

Looking forward to your feedback.
