Improve comments generation + update CI go version

[PaulSonOfLars]

What

Improve docs generation with information from https://tip.golang.org/doc/comment

This should help improve the readability of the docs on pkg.go.dev, as well as emphasize the links to the official tg docs.

As a driveby, update CI go version to ensure local env matches CI.

Impact

• Are your changes backwards compatible? Y
• Have you included documentation, or updated existing documentation? Y (literally the point of the PR)
• Do errors and log messages provide enough context? Y
