x/pkgsite: golang.org redirects /pkg/foo/ to another redirect #54081
Description
The golang.org /pkg/ redirect pages redirect to another redirect:
bradfitz@book1pro ~ % curl -I https://golang.org/pkg/crypto/tls/
HTTP/2 301
content-type: text/html; charset=utf-8
location: https://go.dev/pkg/crypto/tls/
date: Wed, 27 Jul 2022 02:23:28 GMT
server: Google Frontend
But that location (https://go.dev/pkg/crypto/tls/) serves another redirect:
bradfitz@book1pro ~ % curl -I https://go.dev/pkg/crypto/tls/
HTTP/2 307
content-type: text/html; charset=utf-8
location: https://pkg.go.dev/crypto/tls
date: Wed, 27 Jul 2022 02:24:40 GMT
server: Google Frontend
Just have golang.org redirect to the version without the trailing slash instead?
