fix(telega): don't auto-install at init; let MELPA staleness slide

The use-package form defaulted to `:ensure t`, which made init crash when MELPA's archive index pointed at a dated snapshot tarball (`telega-20260503.1332.tar`) that had already rotated off the server -- the install fetch hit a 404 and took the whole startup down with a `file-error`.

Switched to `:ensure nil` so the module configures telega without trying to install it. The `:commands telega` autoload stub still wires `C-; G`; pressing it before the package is installed signals a void-function instead. Commentary now documents the one-time install (`M-x package-refresh-contents` + `M-x package-install RET telega`).
