Made S3Bucket._resolve_path Windows-friendly

[dominictarro]

Read/write from Windows OS produced object keys with backslashes and no folder hierarchy. This was due to pathlib inferring backslashes on Windows when joining bucket_path. Backslashes are frowned upon in the AWS Object key naming guidelines.

Explicitly made Path join bucket_path POSIX path string.

Thank you for contributing! Do you mind fixing other calls to str()?

For example:

prefect-aws/prefect_aws/s3.py

Line 536 in 121ae3d

await self.write_path(str(remote_file_path), content=local_file_content)

prefect-aws/prefect_aws/s3.py

Line 677 in 121ae3d

return str(Path(self.bucket_folder) / bucket_path)

And more

Also can you add a unit test around here?
