Describe your motivation

we have a long project list to update after each releases. creating a script to update those would make our life easier.

(ideally.. this script can handle Testbench, spring etc dependency updates.)

[ZheSun88]

one way that we can use in maven projects is , for example

mvn versions:use-latest-versions -DallowMajorUpdates=true -DgenerateBackupPoms=false -Dincludes=com.vaadin:license-checker

for platform, it should be something different to update the versions.json, for example using the updateVersions.py

FYI @TatuLund, maybe something similar can be done for V7/8.

V7 / V8 are two of the many projects that should be handled
