feat: add if filePatternAssociation

[p-spacek]

What does this PR do?

this PR adds the ability to extend 'schema if condition' with filePatternAssociation. it means that it's possible to extend if condition to be connected to some yaml filename.

basically, it's something similar to yamlValidation: [{filematch, url}] to find whole schema based on yaml filename, but this feature is for finding subschema based on the yaml name.

I added this because my schemas are dynamically created and I need some small modifications inside the schema based on the filename.

     {
          type: 'object',
          title: 'basket',
          properties: {
            name: { type: 'string' },
          },
          if: {
            filePatternAssociation: '*fruit.yaml',
          },
          then: {
            properties: {
              pineapple: { type: 'string' },
            },
            required: ['pineapple'],
          },
          else: {
            properties: {
              carrot: { type: 'string' },
            },
            required: ['carrot'],
          },
        }

yaml: some-fruit.yaml

name: some fruit
pinnaple: 'ok'

yaml: some-vegetable.yaml

name: some vegetable
carrot: 'ok'

I hope it can be useful for you too.
