Fix: normalize version for npm ci

[teppeis]

npm install and creating a patch, then npm ci fails:

patch-package 6.0.2
Applying patches...

Warning: patch-package detected a patch file version mismatch

  Don't worry! This is probably fine. The patch was still applied
  successfully. Here's the deets:

  Patch file created for

    google-closure-library@20190121.0.0

  applied to

    google-closure-library@v20190121.0.0
  
  At path
  
    node_modules/google-closure-library

The original version of the package.json is v20190121.0.0.

This issue is caused by difference between behavior of npm install and npm ci.
npm install normalizes version in package.json of deps (v20190121.0.0 is changed to 20190121.0.0) but npm ci doesn't (just v20190121.0.0).

This PR normalizes the version with semver.
