Add Go 1.25 to CI pipeline

sys/kern/kern_pledge.c r1.329[0] removed the unveil bypass for "dns",
so "rpath" is needed for Go's DNS to stat(2) it.

Since current "/ rwc" and "cpath" with the new "rpath" amount to full
read access, there is no point in unveiling anymore.

+## [0.5.12] - 2024-12-18
+
+* Go 1.22 is now required to build Yggdrasil
+
+### Changed
+
+* The `latency_ms` field in the admin socket `getPeers` response has been renamed to `latency`
+
+### Fixed
+
+* A timing regression which causes a higher level of idle protocol traffic on each peering has been fixed
+* The `-user` flag now correctly detects an empty user/group specification
+
+## [0.5.11] - 2024-12-12
+
+### Added
+
+* Support for `unveil` and `pledge` on OpenBSD
+
+### Changed
+
+* The parent selection algorithm now only chooses a new parent if there is a larger cost benefit to doing so, which should help to stabilise the tree
+* The bloom filters are now repropagated periodically, to avoid nodes getting stuck with bad state
+
+### Fixed
+
+* A memory leak caused by missed cleanup of the peer response map has been fixed
+* Other bug fixes with bloom filter propagation for off-tree filters and zero vs one bits
+* TLS-based peering connections now support TLS 1.2 again
+
 ## [0.5.10] - 2024-11-24
