nix: make status-go version regex even more lax

In release `1.7.0` we had an issue with `status-go` version `v0.62.3.hotfix.3`
not matching [Semantic Versionig](https://semver.org/#spec-item-11) so a fix was
introduced in https://github.com/status-im/status-react/pull/11331 that made the regex a bit more lax.

Again in `1.9.0` we had the same issue and the release not appears as `develop`
instead of the actual `status-go` version, which this time was `0.63.8+hotfix.2`.
Notice the `+` instead of `-` or `.` before `hotfix.2`.

I've added `+` to allowed characters after the 3 digit standard version format.
