feat: fallback to text format implemented for Telegram notifications

[mralien]

fix #3064, #3100

Description

Added fallback to simple text notification for Telegram channel.
Sometimes sendPhoto API method returns 400 error with "wrong file identifier/HTTP URL specified" description while in reality poster is available, and in result no one receives notifications related to this request.

Example 1 (successful photo notification): The Woman King (2022), tmdb:724495
Example 2 (failed photo notification, falling back to text): Hex (2022), tmdb:988233

To-Dos

• Successful build yarn build
• Translation keys yarn i18n:extract / nothing related to UI was changed
• Database migration (if required)

Issues Fixed or Closed

• Fixes Overseer failed to send Telegram notification to a speci user... #3064
• Fixes When sending a notification fails due to a bad request (like it can't find a title), it should still send a notification #3100

For some reason after I built and redeployed my overseerr instance with master + cherry-pick of my commit, even Hex movie start working. But while I was testing everything with plain 1.30.1 it didn't.

For some reason after I built and redeployed my overseerr instance with master + cherry-pick of my commit, even Hex movie start working. But while I was testing everything with plain 1.30.1 it didn't.

To clarify, is this PR still needed? Or is it working as expected?

[mralien]

I think this PR still needed. Even though Hex (2022, tmdb:988233) works right now with latest official docker image, media without poster at all doesn't produce Telegram notifications - checked on movie (or short movie) HEX (tmdb:593281).

It wouldn't harm either way, because no one can predict when and why poster for any movie/TV show might become unavailable.

update: rebased branch on current develop state

I can confirm this is still needed.
