Remove deprecation notice for __experimentalImageSizeControl referencing private API replacements

[peterwilsoncc]

Description

In WordPress 6.3 a deprecation notice was added to wp.blockEditor.__experimentalImageSizeControl referring developers to wp.blockEditor.privateApis.DimensionsTool and wp.blockEditor.privateApis.ResolutionTool.

As these are private APIs, they're unavailable to extending developers so it's not possible to act upon the deprecation notice.

The deprecation notice ought to be removed until the private APIs are made public and extenders can act upon the notice.
