Copying over from the main PR:

Does the following:

• Update minimum engines to 18
• Upgrades package versions as far as possible without hitting esm modules or >18 reqs
• Fixes dangling promises where simple, adds void to others to keep stuff going
• A ton of linter changes for trailing commas in parameter lists (the vast majority of the changes)
• Fully moves typeless-bot support out of the OwlBot process; run by hand
• Updates gapic (autogen) classes from latest generator version
• Also, due to the above, adds gapic-level debug logging support

A couple of breaking changes for Pub/Sub code will be coming shortly as well, nothing major. (Well, major version major, not changes required major :) )

• Remove (broken) legacy OTel support
• Remove legacy ack deadline options, and move maxExtension into subscriber options

🤖 Created releases:

• v5.0.0

@feywind what about documentation? https://cloud.google.com/nodejs/docs/reference/pubsub/latest

I don't see the new option maxExtensionTime here. Could you document it please?
