We should make using addons less confusing for the users.

Describe the solution you'd like

I suggest the following roadmap:

• Make alias three/addons/, pointing to three/examples/jsm/ (Examples: add three/addons/* alias #23406),
• Change the documentation to use word "addons" instead of "examples" and tell only about the alias ("Officialize" renaming of examples classes to addons #24579),
• Update manual (Manual: Change examples to addons. #24888),
• Possibly update documentation paths,
• Move the fonts from examples/fonts, on which addons are dependant (if there are such? Not sure whether it is still the case) to examples/jsm.

After import maps would be supported by Safari and Firefox In the end of the year:

• Finally drop support for examples/js (Remove examples/js. #25043),
• Move examples/jsm/ folder to the root of the repo and rename it to addons, making it less confusing for users reading the source code of the addons.
