Update the repository for the new RoboCup set up

[ysims]

The new RoboCup set up uses

• Webots R2022b (release is on GitHub)
• hlvs_webots repository from the TC, containing the robocup environment files

This PR

• Removes the webots subtree (get the R2022b release rather than building from source)
• Converts the NUgus proto files to R2022b version
• Updates the robocup field proto based on the hlvs_webots repository, keeping in (and updating) our changes for vision data collection. Note: proto scriping now uses JavaScript rather than Lua.
• Updates the kid world with new protos and the externproto declarations

There are many files changed because the subtree has been removed. You can view the individual commits to see what else has changed.

Documentation update at NUbots/NUbook#273

@Tom0Brien I have got it moving through the states past SET now. I sync'd the NUbots fork of hlvs_webots with the original and also pulled GameController and ran ant again, then it seemed to work.

Can I get another review/approval? Had to fix up merge conflicts with the vision PR going in.
