Azle 0.22.0

[lastmjs]

• Make sure to test the compile_typescript_code path.join on Mac, there's a comment to make sure that this works
• dfx extensions documentation #1761
• we need to fix the azle autoreload to use a special identity like file uploading (do this before the next release 0.22.0)
• explain the get/post/composite query cross-canister call rules
• make a documentation chapter explaining how to get the latest Azle updates without waiting on npm

uploader_identity.js:

// TODO reload_js should also use the same kind of pattern here
// TODO...but we don't want to add the controller every time...
// TODO and asking about the controllers each time is not very good
// TODO so maybe we just keep things as they are with auto reload?
// TODO maybe we add an AZLE_AUTORELOAD_UNAUTHENTICATED for those where
// TODO their dfx identity will not work?
// TODO or maybe we just go back to not authenticating and it's really just
// TODO meant to be for development...and we put the warning back...
