Rename the warning message on partial cleanup policy runs

Context

When processing container repositories with a large number of tags, tag cleanup policies will perform multiple partial executions to process tags in small batches.

Problem

When a partial cleanup occurs, the UI shows the following:

While the tooltip message is helpful, displaying Cleanup timed out (i) can be misleading. To me this makes it sound like a fatal/unexpected error was encountered.

Proposal

🔽 design below

• Message displays when cleanup will continue by as selected by the user. List of cadences. For example, the message could say within 24 hours or within 12 hours depending on what the user has set
• The learn more link will require us to add more information about how the tags cleaned up are truncated to this area of the docs.
