use clickable links in documentation, fix list styling (#4955)

* Update comment styles

1. Use doc links (the square brackets around identifiers) to make
   clickable links on pkg.go.dev (https://go.dev/doc/comment#doclinks)
2. Indent lists so that they are rendered properly -- at which point go
   fmt updates the bullet character to a dash
   (https://go.dev/doc/comment#lists)
3. Add a couple missing punctuation marks

These all will improve the experience of browsing the quic-go docs on
pkg.go.dev.

* ignore SA1019 for the ConnectionTracingID

* ci: exclude ConnectionTracing(ID, Key) from staticlint in http3
