feat: add ifttt docs

[jakcinmarina]

Documentation for IFTTT and Apify integration.

I've rewritten the doc to fix few issues like:

• Actor capitalization
• Fix formatting
• Restructure it for better flow
• Added docusaurus admonition

Apart from that I have few questions

1. I assume this is IFTTT default light mode scheme? If yes that is unfortunate but nothing can be done about it.
2. I noticed discrepancies on the screenshots, sometimes it's Actor and other times it's Actor, would be great to unify it to Actor.

Hey @TC-MO , regarding the questions:

1. yeah I haven't seen any option to change the theme. The light theme is there by default but Apify service uses black as the main colour so that's why in places it might look like dark theme. This is needed cause the logo of service is white so there needs to be some contrast.
2. Sorry, not sure about the issue with screenshots, in all places in this sentence I see Actor :D Is it some capitalisation issue or?

I will implement now the requested changes, thank you for the suggestions!

Oh I see that I misstyped in my original comment , I apologize for that. I meant that sometimes it is written Actor and sometimes actor ,and that it would be great to unify it to Actor
