feat: Add tunnel by default (#4399)

* feat: Add tunnel by default

If an access URL is not specified, we will always tunnel.

This is from community-member feedback who exclaimed that
it's confusing having the default for `coder server` display
a warning message, and I agree.

There is very little (maybe none) in running `coder server`
without tunnel and without an access URL, so this seems like
overall a much better UX.
