Clear saved prompt value without changing the namespace or key

Add the ability to clear the value saved under the current key if a value currently exists.

I have some environment variables that differ per user, but stay pretty consistent (think customer account ID or similar), so prompts with storage is perfect, but I can’t seem to find a good way to clear the currently saved value under a particular namespace and key.

Example: Value for CUSTOMER_ID which stays pretty consistent for a given user, workspace, and environment, but does change for particular use cases where a user has access to customer-a and customer-b.

${[ prompt.text(label='Customer ID', store='forever', namespace=b64'ABC123…zz=', ttl='0', placeholder='my-customer') ]}

An interesting alternative could be an advanced option to show the prompt popup every time with the saved value filled-in if one existed.
