Autocompleter (slash command) doesn't respect allowed_block_types

[noisysocks]

Issue Overview

The blocks autocompleter (what you get when you type a /) doesn't respect the allowed_block_types filter.

Steps to Reproduce (for bugs)

2. Add the following to the top of lib/load.php:

add_filter( 'allowed_block_types', function() {
	return [ 'core/paragraph', 'core/image', 'core/quote' ];
} );

2. Create a post
3. Press /

Expected Behavior

Only the Paragraph, Image and Quote bugs should appear in the dropdown.

Shared blocks should be properly filtered when using allowed_block_types filter.

Current Behavior

All blocks should appear in the dropdown.

If you limit the blocks which can be shown using the allowed_block_types filter then shared blocks do not appear in the 'Shared' block inserter tab.

Possible Solution

The getInserterItems selector will correctly filter out non-allowed blocks if you pass the editor setting as its second argument.

#5893 is also related. Probably a dupe actually.

[noisysocks]

I don't think it's a dupe. #5893 is referring to shared blocks not appearing in the inserter when allowed_block_types is set to false, whereas #6070 is referring to all blocks mistakenly appearing in the / command regardless of what allowed_block_types is set to.
