fix(clusterstatus): update deps and bump Go to 1.23

[umesh-khatiwada]

This PR updates Clusterster Status dependencies and upgrades the project’s Go toolchain from 1.19 to 1.23 to align with the current stable Go release line and its standard-library/runtime/toolchain improvements. go

What changed

• Bumped Go version from 1.19 → 1.23 (e.g., [go](https://go.dev/doc/go1.23).mod go directive / CI Go version). go
• Updated Go module dependencies to versions compatible with Go 1.23. [go](https://go.dev/doc/go1.23)

Why

• Go 1.23 is the current stable release line and includes broad runtime/library/toolchain improvements that we want to pick up as part of routine maintenance. go

Notes for reviewers

• If go mod tidy introduces or adjusts a toolchain directive, ensure CI/dev environments are on a Go version that understands it (older tooling can error on toolchain or on go 1.23.0 formatting).

• Verify builds/tests and any container images or CI runners are updated to install Go 1.23. [go](https://go.dev/doc/go1.23)
