Li LiuandGitHub c819a2c5e1 build(deps): upgrade go toolchain to 1.26.5 (#51271)
## What
- Upgrade the root, pkg, client, test, and telemetry example modules
from Go 1.26.4 to Go 1.26.5.
- Upgrade CPU/GPU builder Dockerfiles, macOS CI Go setup, KRTE build
arg, rpm setup, meta-migration builder, and go-client test image to Go
1.26.5.
- Point CPU and GPU builder consumption in `.env` to the successful
build-env tag `20260714-c135601`.

## Why
- Latest direct Trivy scan of
`milvusdb/milvus:master-20260711-1993feae-amd64` reports CVE-2026-39822
in Go stdlib 1.26.4, fixed in 1.26.5.
- The normal daily image scan is currently blocked through Jenkins
`milvus_scan_image_daily` #540 with `exec format error`; last successful
scan is #508 from 2026-06-10, so this was verified by direct image scan.

## Image coverage
- Go toolchain fixes are shared by all Milvus runtime images; no per-OS
runtime Dockerfile package change is required.
- Builder definitions are updated for CPU ubuntu22.04, ubuntu20.04,
ubuntu24.04, amazonlinux2023, rockylinux9 and GPU ubuntu22.04,
ubuntu20.04.
- No runtime image variant is deliberately skipped; this is not an
OS-package CVE.

## Verification
- `go.dev/dl/?mode=json&include=all` confirms go1.26.5 is stable and
linux amd64/arm64 tarballs exist.
- `go env GOTOOLCHAIN GOVERSION` selects `auto` / `go1.26.5` after the
module update.
- `go list -m` succeeds for root, pkg, client, tests/go_client, and both
telemetry examples.
- `cd pkg && go test -tags dynamic,test -gcflags="all=-N -l" -count=1
./util/typeutil` passes after rebasing onto the latest upstream master.
- Jenkins build-env #40 succeeded and published builder tag
`20260714-c135601`; `.env` now selects that tag for CPU and GPU CI
builds.
- A repo-wide audit found no remaining Go 1.26.4 toolchain pins.

Note: full root `go mod tidy` is not included because this checkout has
a root-owned `deployments/docker/dev/volumes/etcd/member` directory that
makes `go mod tidy` fail with permission errors; `go mod tidy -e`
subsequently OOMed locally. No go.sum changes were produced by the
successful module tidies.
