feature: Add friend fast delete feature

[o3LL]

Hi, I was trying to get used to the project by adding some feature that was a nice-to-have.
Since it's working well, I through it should be nice to open this PR!

Feature
I added an "x" cross to delete players directly from the friend-list.

What I probably missed:

• I don't have many friends, this feature may need to be tested with a huge friend-list since it use infinite scroll loading.
• I didn't added any tests, I don't know about this project test requirement. If needed I should be able to add some.
• Page loading, this feature may not work in modal since I don't know how to open one 😨
• That's my first try with React inside a browser extension, I may have used anti-pattern or anything else, help welcomed 👍

What I also added:

• I updated fetch wrapper to be able to add the request method as an argument, this shouldn't have any impact on other request using the wrapper.
