x/pkgsite: example code should be displayed as package main when rendering

[fishy]

What is the URL of the page with the issue?

https://pkg.go.dev/github.com/reddit/[email protected]/thriftclient?tab=doc#example-package

What did you expect to see?

On godoc.org, the Example* functions will be renamed to main when rendering, for example: https://godoc.org/github.com/reddit/baseplate.go/thriftclient#example-package

What did you see instead?

On pkg.go.dev we kept the original Example function name in the code.

If you would like to test it out locally, you can run go run ./devtools/cmd/experiment create executable-examples.

The output should look like this:
