Ensure all NPM packages have readmes included in their builds (#2156)

## Motivation for the change, related issues

This PR ensures all public package builds include a  README.md file,
because some of our NPM packages don't include a readme on the npmjs.com
package page.

The readmes exist in project folders, but before this PR they were not
added to the built version of the package.

## Implementation details

Add `build:README` step to these public packages:

- @php-wasm/cli
- @php-wasm/progress
- @php-wasm/scopes
- @php-wasm/web-service-worker
- @wp-playground/blueprints
- @wp-playground/cli
- @wp-playground/client
- @wp-playground/components
- @wp-playground/remote
- @wp-playground/sync

## Testing Instructions (or ideally a Blueprint)

- Remove the `dist` folder if it exists
- Run `npm run build`
- Check that all PHP-wasm builds have a README.md
```
find dist/packages/php-wasm -mindepth 1 -maxdepth 1 -type d '!' -exec test -e '{}/README.md' \; -print
```
- The above command should only return
`dist/packages/php-wasm/out-tsc-phpwasm-node` which isn't a package
- Check that all Playground builds have a README.md
```
find dist/packages/playground -mindepth 1 -maxdepth 1 -type d '!' -exec test -e '{}/README.md' \; -print
```
- The above command should only return
`dist/packages/playground/website` which isn't a published package
