./bin/watch-storefront.sh missing

I did find a solution I did check between the psh.phar commands and found a storefront:hot-proxy command.

during execution I received the following error:

        Browserslist: caniuse-lite is outdated. Please run:
        npx browserslist@latest --update-db

So I installed the browserlist npm package,
updated it by running:

        Browserslist: caniuse-lite is outdated. Please run:
        npx browserslist@latest --update-db

And finally I executed the ./psh.phar storefront:hot-proxy successfully.
