docs(@angular/cli): generalize project argument description for architect commands

The `project` positional argument is shared by `build`, `serve`, `test`, `lint`,
`e2e`, `deploy` and `extract-i18n`, but its description read "The name of the
project to build." for all of them. Use wording that applies to every command.
