fix: remove parentIsObject() check (#12851)
we will allow situations such as ``` a/b/1.txt a/b ``` and ``` a/b a/b/1.txt ``` we are going to document that this usecase is not supported and we will never support it, if any application does this users have to delete the top level parent to make sure namespace is accessible at lower level. rest of the situations where the prefixes get created across sets are supported as is.

## MinIO Server Limits Per Tenant
|

For best deployment experience MinIO recommends operating systems RHEL/CentOS 8.x or later, Ubuntu 18.04 LTS or later. These operating systems package the latest 'xfsprogs' that support large scale deployments.

### Object name restrictions on MinIO
|
||||
Object names that contain characters `^*|\/&";` are unsupported on Windows and other file systems which do not support filenames with these characters. NOTE: This list is not an exhaustive, it depends on the operating system and filesystem under use.
|

- Object names that contain characters `^*|\/&";` are unsupported on Windows platform or any other file systems that do not support filenames with special charaters. **This list is non exhaustive, it depends on the operating system and filesystem under use - please consult your operating system vendor**. MinIO recommends using Linux based deployments for production workloads.
|
||||
|
||||
For best experience we recommend that you use distributions that ship fairly recent Linux kernel such as CentOS 8, Ubuntu 18.04 LTS along with XFS as the choice for your backend filesystem.
|
||||
- Objects should not have conflicting objects as parents, applications using this behavior should change their behavior and use proper unique keys, for example situations such as following conflicting key patterns are not supported.
