[BUG] UI: make explicit description for default retention for buckets

[giubacc]

Describe the bug A clear and concise description of what the bug is.

Minor issue, but IMO worth to be addressed.
When creating a bucket and setting the default retention mode, I would make explicit that this is a default retention mode.
Let's keep in mind that this setting can be changed at any time. Also user can decide, explicitly, with the APIs to not even put a retention over an object (or/and over a specific version); that is completely optional.
Default retention mode only says that when there isn't an explicit setting from the user, the object takes the current default retention mode.
The current description suggests that every object will take the retention set there.
So I would change that.

The current description suggests that every object will take the retention set there.

Any suggestions on how to word the notice text instead?

[giubacc]

My suggestion, something like:

Title: "Default bucket retention mode"
SubTitle: "Applied to any object put without an explicit retention mode set"
