fix: support deeply nested pnpm virtual store node_modules paths in resolveAndRunNgcc (#1742)

Uses indexOf instead of lastIndexOf in resolveAndRunNgcc.

This resolves the case where a user is using pnpm and ngcc is resolved through symlinks to a deeply nested virtual store node_modules location:

`some/user/path/node_modules/.pnpm/@angular/[email protected]/node_modules/@angular/compiler-cli/...`

lastIndexOf would resolve to `some/user/path/node_modules/.pnpm/@angular/[email protected]` which is incorrect. indexOf gets you to the desired `some/user/path`
