feat: specify linked deps in shrinkwrap.yaml

We need info about linked packages to make pnpm recursive commands more deterministic. With this changes, when packages are linked in, the shrinkwrap.yaml file of the target package is updated. For example, foo is linked into bar, shrinkwrap.yaml of bar will be:

dependencies:
  foo: link:../foo
registry: 'https://registry.npmjs.org/'
shrinkwrapMinorVersion: 4
shrinkwrapVersion: 3
specifiers: {}

TODO:

[x] the link function should link several packages to minimize the number of operations on the shrinkwrap
[x] node_modules has to be pruned after linking
[x] ~don't run the link() function after installation~

pnpm / supi
