fix(tgbot): use a token telego accepts in the edit-message tests

telego.NewBot validates the token against `^\d+:[\w-]{35}$` before any
option is applied, so the "test-token" literal in the two
not-modified tests failed with "telego: invalid token format" and the
go-test and race jobs went red on every run since #6340. Use a
placeholder token that matches the format; the tests now reach the
mock API server, pass with the guard in place and fail without it.
