imagetools-core 4.0.4 `resolveConfigs` behavior change, `format` directive no longer working

[Jared Moore]

Hi, in 4.0.3:

resolveConfigs([ [ 'w', [ '5', '10' ] ], [ 'format', [ 'webp', 'avif', 'png' ] ] ], {})

equals

[
  { w: '5', format: 'webp' },
  { w: '5', format: 'avif' },
  { w: '5', format: 'png' },
  { w: '10', format: 'webp' },
  { w: '10', format: 'avif' },
  { w: '10', format: 'png' }
]

However, in 4.0.4, format is no longer parsing:

[
  { w: '5' },
  { w: '5' },
  { w: '5' },
  { w: '10' },
  { w: '10' },
  { w: '10' }
]

I don't see any notes on format's behavior changing. I believe this diff might be the cause of this new behavior:
