feat(devkit): add a flag to keep existing versions when calling addDependenciesToPackageJson

[jaysoo]

This PR adds a flag to addDependenciesToPackageJson function in devkit to prevent versions from being bumped. This will be used in init generators since using nx init and nx add should not bump versions and risk breaking existing projects.

Example:

If existing package.json already has [email protected], then calling this function:

addDependenciesToPackageJson(
  tree,
  {
    next: '~14.0.0'
  {},
  undefined,
  true // keepExistingVersions
);

Will leave next at existing version of 13.4.0.

Notes

• There was discussion on converting the args to accept an options object, but this will break existing usages with signature addDependenciesToPackageJson(tree, {...}, {...}, customPackageJsonPath), unless we do function overrides.
