fix(ng-dev/release): ensure installed node modules do not break withi…

…n Bazel

This commit fixes an issue where old modules from other version branches
are preserved in the `node_modules` of a newly checked-out version
branch. Old/extraneous modules can cause the Bazel NodeJS rules to throw
with an error when preparing the `@npm//` workspace.

Yarn v1 has a bug where nested node modules are not cleaned properly.
Yarn v2+ supposedly fixes that, but for now we are still on v1.x and
in general it seems more safe to clean the node modules.

Here is the related Yarn bug: yarnpkg/yarn#8146.
Here is an example Bazel NodeJS error:
