caddy: upgrade to 2.3.0
As there is currently a bug with go build info
(https://github.com/golang/go/issues/29228) a patch is needed to
fix printing the correct version number of the binary. Once the bug is
fixed, the patch can be dropped.

Fix for #22092

If GitHub CI cannot be used to validate the build result (for example, if the
build is likely to take several hours), make sure to
[skip CI](https://github.com/void-linux/void-packages/blob/master/CONTRIBUTING.md#continuous-integration).
When skipping CI, uncomment and fill out the following section.
Note: for builds that are likely to complete in less than 2 hours, it is not
acceptable to skip CI.
