fix(core): improve running migrations for older workspaces

[leosvelperez]

Current Behavior

Starting on Nx 15.7.0, Nx DevKit generators can only write to project.json files. When it comes to migrations, workspaces in older versions that are using the config format v1 and are migrating to a version lower than 15.7.0 have issues with any migration generators written with Nx DevKit and using updateProjectConfiguration. In those cases an error is thrown because the project.json file (expected by latest Nx) doesn't exist. This happens because migrations are always run with the latest version of Nx.
Workspaces migrating to a version lower than 13.9.0 don't get @nrwl/tao version bumped which is a package needed for those versions.
Workspaces using an Nx version older than 14.0.0 when migrating to a version higher than 14.0.0 don't get any package update unless the package is explicitly set in the command nx migrate @nrwl/workspace@<version>.

Expected Behavior

Migrating a workspace to an older version than 15.7.0 should succeed. In those cases, the migrations would be run with the local installation of Nx.
The @nrwl/tao package should be updated when migrating to an older version of Nx where that package is required.
Migrating running nx migrate latest should work regardless of the version, explicitly specifying the package to update Nx should not be required.

Can we pin to latest 15.6.X instead of the local version?
