fix(@angular/build): use sha256 instead of sha-256 as hash algorithm name

Stackblitz appears to fail when attempting to use `crypto.createHash` with
an algorithm value of `sha-256`. Since Node.js supports both the hyphenated
and unhyphenated values, the later is now used to avoid issues when running
on Stackblitz.
