Support scheduled actions

[amiru3f]

Hey there,

Thanks for developing the Telegram integration, but just a quick check, I'm wondering why you ignore the recurring/scheduled triggers by this:

telegram-action/src/main.ts

Line 17 in cc15ab3

if (!Utils.in_array(event, ['push', 'release'])) {

Is that for bombarding prevention or something?

I'm open to submitting a PR to also support recurring jobs namely:

name: Destroy the infrastructure
on:
  schedule:
    - cron: "00 06 * * *"
