Plugin: Ensure that all *.asset.php files are included in plugin.zip

[gziolo]

Description

Fixes a bug reported by @aaroncampbell in #33082 (comment):

I'm still seeing this on WP 5.9-alpha-51272-src with Gutenberg 11.4.1. It looks like it's looking for a gutenberg/build/block-library/blocks/file/view.min.asset.php but no *.asset.php file exists there? Same with with navigation block and probably others although those are the two triggering notices on the plugins page when I click activate.

Core appends the asset.php, and the core blocks seem to have files named accordingly.

How has this been tested?

I executed the command that generates the gutenberg.zip file:

./bin/build-plugin-zip.sh

I checked if the asset files get included:

The same File block looks like this in the build folder:

I think we need to change this line too?

It warns when files are not present:

I think this is why the list for edit-widgets and widgets is shorter.

I would appreciate if we could use the following:

build_files=$(
	ls build/*/*.{js,css,asset.php} \
	build/{block-library,edit-widgets,widgets}/blocks/*.php \
	build/{block-library,edit-widgets,widgets}/blocks/*/block.json \
	build/{block-library,edit-widgets,widgets}/blocks/*/*.{js,css,asset.php} \
)

Unless there is a nice way to hide those warnings.
