proposal: all: end support for macOS 11 in Go 1.25

[cherrymui]

Proposal Details

Go added support for macOS 15 that was publicly released this September. After internal discussion, we believe the summer of 2025 will be a good time to drop support for macOS 11. The last security update it received was in September 2023.

On behalf of @golang/release, I propose we announce the end of support in the Go 1.24 release notes, and disable the builder for Go 1.25. Go 1.24 (security patches until Feb 2026) will be the last release with macOS 11 support.

For context, https://github.com/golang/go/issues/64207#issuecomment-1843590873 contains some history as well as future patterns if we keep the same cadence.
