Bug: Use npm ci command only during CI

[kbeaugrand]

npm ci command is executing during normal build (with visual studio), but the normal behavior of this command line is to remove existing node_modules before installing expected packages.
This is very computing and power consuming rather than npm install command line which is supposed to only install missing dependencies over existing installation.

Expected Behavior

During developement, npm install command should be executing in build phase.
During CI, npm ci command should be executing.

Current Behavior

npm ci is executing in all phases.
