[PATCH v2 03/17] fix: utils: add a substr for the patch media caption

[Muhammad Rizki <kiizuha@gnuweeb.org>]

Add a substr caption for the patch email to avoid MediaCaptionTooLong
for the Telegram bot.

Regarding to commit 125111a7, its forget to add a substring to trim the
media caption for the Telegram bot, because Telegram only allow
media caption to 1024 only, so trim it to 1020.

Fixes: 125111a7 ("daemon: Full refactor everything about scraper")
