dartdoc exception on 2.9.0-1.0.dev

[jcollins-g]

The new format of the SDK version number causes the version parser in pub_semver 1.4.4 to return a different type for the preRelease.first version component.

P0 as this will impact any use of --link-to-remote, which is an important use case for pub.

I'm not sure how it would affect pub.dev, we don't use pre-release versions of the dart-sdk (well, it happens, but we try to avoid it). Maybe, if the package has a lower bound SDK constraint on a pre-release?

In any case, we'll do our best to pick up the next release. Feel free to ping me when this ships.

[jcollins-g]

@jonasf It shouldn't affect pub unless you try to run dartdoc with a dev release -- dartdoc tries to link against the SDK you're running with, rather than anything based on constraints.

Regardless, 0.31.0 has published with the patch, so updating to that should eliminate that worry.
