Use cargo-release and bump minor versions

I'm getting set up with cargo release to help address #8. We don't really need a tool for managing all this yet, since this commit is literally just cargo release version minor --execute. We may want to exclude the test crates from this process, but I don't see much harm in bumping those at the same time.

I'd suggest we set all crates we don't intend to publish to "0.0.0" and put a file like this in the directory: https://github.com/oxidecomputer/progenitor/blob/main/example-build/release.toml

Good idea, thanks @ahl. After ignoring all the internal crates, here's what cargo release will do:

bnaecker@shale : ~/usdt $ cargo release version minor
   Upgrading dof from 0.3.0 to 0.4.0
    Updating usdt's dependency from =0.3.0 to =0.4.0
    Updating usdt-impl's dependency from =0.3.0 to =0.4.0
    Updating usdt-impl's dependency from =0.3.0 to =0.4.0
   Upgrading dtrace-parser from 0.2.0 to 0.3.0
    Updating usdt's dependency from =0.2.0 to =0.3.0
    Updating usdt-attr-macro's dependency from =0.2.0 to =0.3.0
    Updating usdt-impl's dependency from =0.2.0 to =0.3.0
    Updating usdt-macro's dependency from =0.2.0 to =0.3.0
   Upgrading usdt-impl from 0.5.0 to 0.6.0
    Updating usdt's dependency from =0.5.0 to =0.6.0
    Updating usdt-attr-macro's dependency from =0.5.0 to =0.6.0
    Updating usdt-macro's dependency from =0.5.0 to =0.6.0

   Upgrading usdt from 0.5.0 to 0.6.0
warning: aborting release due to dry run; re-run with `--execute`

That's what I really want, and still no need for a script or tool to run that.
