Update README.md

[barisegesevgili]

• Setting up the environment should be more detailed
• Link to the "wikipedia tr pages dump" is exhausted, should be updated
• Access to the wikipedia domain is restricted in some countries, Note about using VPN could be added (can be discussed)

I can take this on, can you tell me more about the tr pages dump and what exactly is it?

I'll be adding small GIFs to illustrate the setting up the environment steps if that's fine with you :)

Thx for your interest! You can work on a new branch then update the GIFs there as you wish. Just add me as reviewer after completion. So we can decide updating accordingly.

I can handle the part about dumps. Its a bit detailed.
