chore: just a quick typo fix

[tightightight]

Before submitting a PR :

1. Ensure your fork is created from master branch of the repository.
2. Run npm install in the root folder.
3. After bug fix/code change, ensure all the existing tests and new tests (if any) pass (npm run-script test-all). During development, to run individual test use node_modules/nodeunit test/<test_file.js> -t <test_name>.
4. Build the driver (npm run build).
5. Run eslint and flow typechecker (npm run lint).
6. Run commitlint (node_modules/.bin/commitlint --from origin/master --to HEAD). Refer commit conventions and commit rules.

Just fixed the spelling of License in the readme <3

[MichaelSun90]

Hi @arthurschreiber, I thought License is spelling differently in British and American English, and both of them are correct. Do we have a constrain for which spelling should be used or either one is OK? If either one is ok, then I think it is safe to close this PR fro now?
