[build] Migrate grunt license:csv_report to script

[jbudz]

Part of a larger effort to remove our grunt depedencies, #85341.

• This will need upstream changes to the release-manager, so we'll have to sync merges
• Testing can be done by checking out f4357c0 and comparing the outputs of the grunt task with the script:

npx grunt licenses:csv_report --csv=$HOME/dev/kibana/foo1.csv  
node scripts/licenses_csv_report.js --csv=$HOME/dev/kibana/foo2.csv

The release manager references the grunt task - so we will want to maybe first migrate the RM to reference the NPM script to ease the transition.
