Support Angular v10

After migrating to Angular v10:

warning "@angular-builders/custom-webpack > @angular-devkit/build-angular@0.901.1" has incorrect peer dependency "@angular/compiler-cli@>=9.0.0 < 10".
warning "@angular-builders/custom-webpack > @angular-devkit/build-angular@0.901.1" has incorrect peer dependency "typescript@>=3.6 < 3.9".

I had the same issue with Cannot find module webpack after upgrading. I didn’t want to run npm link webpack especially on the build server.

What I ended up doing (and worked) was:

npm uninstall --save-dev @angular-builders/custom-webpack
rm -rf package-lock.json
rm -rf node_modules
rm -rf dist # this seems to be important for some reason, I tried the same steps without this before and it didn't work ...
npm install
npm install --save-dev @angular-builders/custom-webpack@10.0.0-beta.0

I can’t say for sure this will work on the first try, as I did some of the steps multiple times, but eventually, it worked without npm link.

After update to 10.0.0-beta.0 I see an error:
