Fix botocore endpoint resolution by preserving top-level data files

[piochelepiotr]

Summary

• PR Delete botocore API schemas that we don't use to save disk space #22283 used botocore/data/* to strip unused service models at build time, but this glob also matched essential top-level files (endpoints.json, partitions.json, sdk-default-configuration.json, _retry.json) that botocore needs to resolve any AWS service endpoint
• Changes the pattern from botocore/data/* (matches files and directories) to botocore/data/*/ (matches only subdirectories), so top-level files are preserved automatically
• Fixes DataNotFoundError: Unable to load data for: endpoints that breaks amazon_msk and kafka_consumer with MSK IAM auth

Test plan

• Verify with pathspec that top-level files are no longer excluded:

  python3 -c "
  import pathspec, tomllib
  with open('.builders/scripts/files_to_remove.toml', 'rb') as f:
      spec = pathspec.PathSpec.from_lines('gitwildmatch', tomllib.load(f)['excluded_paths'])
  for f in ['botocore/data/endpoints.json', 'botocore/data/_retry.json',
            'botocore/data/partitions.json', 'botocore/data/sdk-default-configuration.json']:
      assert not spec.match_file(f), f'{f} should not be excluded'
      print(f'PASS: {f} preserved')
  for f in ['botocore/data/ec2/2016-11-15/service-2.json']:
      assert spec.match_file(f), f'{f} should be excluded'
      print(f'PASS: {f} excluded')
  for f in ['botocore/data/sts/2011-06-15/service-2.json', 'botocore/data/kafka/2018-11-14/service-2.json']:
      assert not spec.match_file(f), f'{f} should not be excluded'
      print(f'PASS: {f} preserved')
  "

• Build agent wheels and confirm botocore/data/endpoints.json is present in the output
• Deploy to a cluster running kafka_consumer + amazon_msk against MSK and verify checks pass
