• bump botocore dependency specification to support
  "botocore >= 1.43.101, < 1.43.107" (#1723, #1728, #1734, #1744, #1759,
  #1764)
• mirror botocore 1.43.98's StreamingChecksumBody changes: skip checksum
  validation when no checksum is expected, and expose the new checksum
  property on streaming checksum bodies (#1744)
• register the S3_REGION_REDIRECT user-agent feature ID when
  AioS3RegionRedirectorv2 follows a region redirect, matching botocore
  1.43.101 (#1759)
• fix AIOHTTPSession.close() raising AssertionError: Session was never entered when called on an already-closed session (e.g. a defensive
  close() inside an async with block), which also masked the user's own
  exception (#1745)
• remove unreachable return statements from the AioRefreshableCredentials
  credential properties (#1762)
