build: update @angular-devkit/build-angular to use commit SHA (#41434)

This is a temporary workaround until the CLI version containing a fix for the regression caused by deacc74 is available on NPM.

Without this change CLI builds will fail with;
```
angularCompiler.getNextProgram is not a function
```

PR Close #41434
