angular: fix readme for dev envs (docker#260)

I accidentally edited the wrong `README`, which was the inner one from the app generated by Angular CLI rather than the project one about Compose. Restored the old one and moved the dev envs info to the root/Compose README. Signed-off-by: Milas Bowman <milas.bowman@docker.com>
