Description
When you create a secret through the UI, a placeholder key is shown. If you don't type anything, the secret is stored as {"":"value"}, making impossible to be readed from a K8s using VaultSecretOperator
Describe the solution you'd like
I'd expect that key is saved with the secret if I don't type anything, as the placeholder indicates
Proposal
I prepared a PR with my proposal, saving the placeholder value key as default: #31619
