Unable to configure "Keep only the last version of the file" lifecycle rule

[jglopez]

If a B2 bucket has its lifecycle settings configured to "Keep only the last version of the file" via the web interface:

Then the provider will unnecessarily require that file_name_prefix be defined and will always instead want to create a custom lifecycle rule.
Error from terraform plan:

╷
│ Error: Missing required argument
│ 
│   on redacted.tf line 6, in resource "b2_bucket" "redacted":
│    6:   lifecycle_rules {
│ 
│ The argument "file_name_prefix" is required, but no definition was found.
╵

Steps to reproduce

1. Create B2 bucket via web interface
2. Configure lifecycle settings: Keep only the last version of the file
3. Import B2 bucket into Terraform state: terraform import b2_bucket.example [bucket_id]
4. Run terraform plan
5. See that terraform requires that file_name_prefix is defined

Whoops! Sorry, just realized this was already reported 🤦

Duplicate of #3

Even with better documentation, this is still really broken. See #85 .

As stated in #3, fileNamePrefix is required to be an empty string in order to apply the rules to every file in the bucket - that why this parameter is required which is aligned with the B2 API
