chore(individual-pkg-gen): set the alpha version in alpha module's pa…

…ckage.json files if present (#16322)

This change sets the `version` key in each alpha module's `package.json` file to the alphaVersion that was created in this PR: #16043

And, also sets the version of each dependency on another alpha module to the same version. 

Depends on: #16321 

Part of: #15591
