Blocklist - Add "Determine updates to apply" toggle to improve the process of detecting block changes

[bobbingwide]

In https://github.com/bobbingwide/oik-update/issues/2#issuecomment-1256140210 I've proposed a new improvement to the semi-automatic process of determining which blocks need to be added, updated or deleted ( or marked as deleted ) when a block plugin has been updated to a new version.

I wrote

• This change will involve the oik/blocklist block, from the oik-blocks plugin.
• There will be another toggle labeled Determine updates to apply
• When selected the block will be dynamically rendered, indicating which of the blocks are new, updated or deleted.
• I need to check what information I can determine from the static HTML generated in the block editor.

Requirement

Improve the semi-automatic process of determining blocks to add, update or delete.

Proposed solution

• Add a new toggle - Determine updates to apply
• When set on then dynamic rendering will compare the list of blocks and variations ( if selected ) with the blocks and variations on the server and produce a report showing the differences.
• This is in addition to whatever's currently displayed.

The server part of this is implemented in oik-shortcodes.
