Timeline: Localization sv_SE, nb_NO with warning

Describe the defect Permanent warning when timeline is loaded: timeline.js.xhtml?ln=primefaces&v=8.0:52 WARNING: options.locales['nb_NO'] not found. See https://visjs.github.io/vis-timeline/docs/timeline/#Localization

This is similar issue as Timeline: Localization pt_BR with warning

Reproducer Set p:timeline property to: locale=“sv_SE” or locale=“nb_NO”

Environment:

• PF Version: 8.0
• MyFaces 2.3.6
• Affected browsers: ALL

To Reproduce Steps to reproduce the behavior:

1. Copy paste timeline example from PF showcase
2. Put locale=“sv_SE” or locale=“nb_NO”

Expectation

1. No warning in the console
2. I can see that PF documentation (since version 8) contains information to add momentum js (/moment.js and e.g. locale/es.js) to localize timeline. Originaly, localization was made by PrimeFaces.locales [PF Wiki ] (https://github.com/primefaces/primefaces/wiki/Locales) (we are using this way since PF 4). Is this way deprecated for timelne? If yes, there is no information in migration guide about this.
3. Maybe it would be good to add to the doc: What is the preferable way of including moment.js into project? Schould be downloaded separately or used that one is included in PF jars already (how)? Link to download moment and locales: CDNJS
