[BUG] .npmrc is generated in all the packages

[rverma-dev]

Describe the bug

With version 0.17.3 onward, projen is also generating .npmrc file in each directory based on https://github.com/sperka/aws-prototyping-sdk/blob/c85312c706e776ef49beed02fa97df3285759cf8/private/projects/pdk-monorepo-project.ts#L174

This lead to unnecessary file generation and warnings

npm WARN ignoring workspace config at /Users/rverma/dev/aws/nsa/packages/demo/.npmrc 

More details of handling this is here npm/cli#4605

This is actually due to a change I made to projen to always create a .npmrc file for PNPM projects so that resolution-mode is set to highest. For reference see the projen issue here projen/projen#2628 and where I upgraded the projen peer dependency version in PDK here: #373

Nevertheless it is annoying having the extra .npmrc files, so I'll send a PR to remove any subproject .npmrc files if you're using the nx-monorepo
