chore: remove eslint-plugin-array-func (#38294)

The rules from `eslint-plugin-array-func` are redundant with
`eslint-plugin-unicorn`:

- `from-map` → `unicorn/prefer-array-from-map`
- `no-unnecessary-this-arg` → `unicorn/no-array-method-this-argument`
- `prefer-flat` / `prefer-flat-map` → `unicorn/prefer-array-flat` /
`unicorn/prefer-array-flat-map` (already disabled here)

The two remaining rules (`avoid-reverse`, `prefer-array-from`) are niche
and not worth carrying an extra dependency for.
