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

Hi, team,

I noticed you are using _eslint-plugin-header_ with the schema-turn-off
workaround to support ESLint 9.

I forked _@tony.ganchev/eslint-plugin-header_ mid-2024 to address this
issue 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`.

I've sent PR proposals to other projects in the cloudscape-design space:
- cloudscape-design/board-components#401
- cloudscape-design/chart-components#185
- cloudscape-design/code-view#122
- cloudscape-design/collection-hooks#136
- cloudscape-design/component-toolkit#200
- cloudscape-design/components#4308
- cloudscape-design/demos#243
- cloudscape-design/jest-preset#58
- cloudscape-design/test-utils#114
- cloudscape-design/theming-core#148

Looking forward to your feedback.
