Scripts: Build command deletes all files and directories in output path

[sjregan]

Description

When running the command wp-scripts build --output-path=assets all files and directories within assets are deleted.

I expect the directories created and populated by the build script to be reset, not other files and directories.

My plugin has the following directory structure:

plugin/assets/
plugin/assets/css/
plugin/assets/images/
plugin/src/blocks/types/block1/
plugin/src/blocks/types/block1/block.json
plugin/src/blocks/types/block2/
plugin/src/blocks/types/block2/block.json

The build script will generate:

plugin/assets/blocks/types/block1/block.json
plugin/assets/blocks/types/block2/block.json

However it will also delete plugin/assets/css/ and plugin/assets/images.

I would expect all the files and directories within plugin/assets/blocks/ to be removed and rebuilt, but not files and directories outside that directory.

Step-by-step reproduction instructions

1. Create a plugin with the directory structure above
2. Run wp-scripts build --output-path=assets
