README.md: Change `release` to `released`

[utkarsh2102]

Last line here mentions:

Any code in this repository is to be release under the MIT license.

The word release should be changed to released.

A good newcomer issue.

I’ll do this as well as a proofreading of the readme.

Edit: Now I know that wasn't exactly up to protocol. My bad.

Sorry to all the maintainers about the closed PR's.

I have read the commit message guidelines but I could not get the PR correct

[asrdav]

I tried all the headings such as:
1.)Change release to released in README.md
2.)README.md: Change release --> released
3.)Change release to released in README.md

Could anyone tell where should I make the change?
