[onuralpszr]

Description

Hello, 👋 , After long testing,user experiences and problems, we decided to remove opencv-python-headless package from supervision and using full version opencv, it is easy swap headless version If user desired to or wants to use distro version of opencv if wished to, we had so many cases bring more problem than gain and I think around 20mb~ bigger package won't be a big problem as well. Thank you so much

I believe the lockfile needs to be updated as well.

Upon freshly cloning it and attempting to install the deps, here's what I get:

pyproject.toml changed significantly since poetry.lock was last generated. Run `poetry lock [--no-update]` to fix the lock file.

@LinasKo tests are done, index.md corrected (with some small ui fix), merge complete, lock file done as well.

I installed, ran the tests, and built the docs, spotting no regressions.

Good catch regarding the index page.

I saw some changes in markdown formatting, but that's fine.

Merging. Thank you @onuralpszr!
