We currently generate invalid workflow commands when we create
annotations with a `title` but no `file`. Let's fix that.
While we're here, let's improve handling of `title`s with `:`s. We
cannot use `title`s with `::` since GitHub Actions uses this as a
separator for different fields between a workflow command.
Let's also make sure `metadata` never ends in a `:` to avoid confusing
the GitHub Actions command parser about where the `::` separator is
meant to be.
I previously added the 8 curl exit code (weird server reply) to the
list of non-success exit codes that `#curl_headers` will handle.
We're now seeing failures with a 56 exit code (failure in receiving
network data), where the server returns a 4xx response for a `HEAD`
request but the same request using `GET` works as expected (e.g.,
casks like `beeper`, `get-api`, `odrive`, `ui`, etc.).
This adds 56 to the list of exit codes in `#curl_headers`, so a
response with a 4xx HTTP status will be automatically retried using
`GET`.
