Adding the updateInternalDependents=always option to the version command

[ktzouno]

Hi,

I'm interested in converting an existing polyrepo to a monorepo and I'm investigating how close Changesets is to our existing flow. One of the missing parts I noticed is the possibility to tolerate out-of-range dependencies and offer to update them.

i.e.

pkg-a (private): 1.0.0
  * depends on pkg-b: "2.0.0"
pkg-b (public): "10.0.0"

We update pkg-b to version 11.0.0.

Current behavior

Changesets will log an error and won't bump pkg-a to the upcoming pkg-b@11.0.0:
Package "pkg-a" must depend on the current version of "pkg-b": "10.0.0" vs "2.0.0"

Expected behavior

Changesets will log a warn but still bump pkg-a to the upcoming pkg-b@11.0.0:
Package "pkg-a" must depend on the current version of "pkg-b": "10.0.0" vs "2.0.0"

I noticed the already existing experimental setting "updateInternalDependents": "always" which seemed relevant, so I piggy-backed on it and implemented the feature. Is that going to the right direction so I can continue working on a formal PR (tests, docs, etc.)?
