Add compatibility with eslint 9

[simon-abbott]

Eslint 9 requires that all rules have an options schema. Since this package doesn't have one, configuring the rule gives the error:

Configuration for rule "header/header" is invalid:
Value ["block",["--snip--"],2] should NOT have more than 0 items.

Is there any way for us to disable the schema validation from our side

I have applied this patch via patch-package:

Unfortunately the original issue got closed by maintainers: #57

I had to fork the package to add ESLint 9 support - https://www.npmjs.com/package/@tony.ganchev/eslint-plugin-header
