feat(eslint-plugin-react-components): support granular lib imports

[mainframev]

Some partner codebases have a lot of @fluentui/react/lib/* imports. The current implementation of this rule only inspects @fluentui/react imports, so these usages are not detected and no errors / warnings are reported.

Previous Behavior

@fluentui/react/lib/* imports were ignored

 FAIL   eslint-plugin-react-components  src/rules/prefer-fluentui-v9.spec.ts
  prefer-fluentui-v9
    valid
      ✓ import type { IDropdownOption } from '@fluentui/react'; (23 ms)
      ✓ import type { ITheme } from '@fluentui/react'; (3 ms)
      ✓ import { ThemeProvider } from '@fluentui/react'; (1 ms)
      ✓ import { Button } from '@fluentui/react-components'; (1 ms)
    invalid
      ✓ import { Dropdown, Icon } from '@fluentui/react'; (4 ms)
      ✓ import { Stack } from '@fluentui/react'; (2 ms)
      ✓ import { DatePicker } from '@fluentui/react'; (1 ms)
      ✕ import { CompoundButton } from '@fluentui/react/lib/Button'; (3 ms)
      ✕ import { Stack } from '@fluentui/react/lib/Stack'; (3 ms)

  ● prefer-fluentui-v9 › invalid › import { CompoundButton } from '@fluentui/react/lib/Button';

    assert.strictEqual(received, expected)

    Expected value to strictly be equal to:
      1
    Received:
      0

    Message:
      Should have 1 error but had 0: []

    0 !== 1

New Behavior
