Replaced "requireements" to "requirement" in installation.rst
The highlighted word in the screenshot is wrong so I replaced it with the correct one.

@akhilsahuji the DCO check is failing because you need to sign-off your commit. The Details link by the check has instructions for how you can fix it: https://github.com/AcademySoftwareFoundation/OpenColorIO/pull/1632/checks?check_run_id=6056478833
Also see the commit sign-off instructions in our CONTRIBUTING document: https://github.com/AcademySoftwareFoundation/OpenColorIO/blob/main/CONTRIBUTING.md#commit-sign-off
@michdolan I think it should merge now.
Thanks @akhilsahuji . Your commits still need a sign-off to pass the DCO check. It will require amending your commits and force pushing to your branch. Please see the Details link beside the failed check for instructions on fixing.
@michdolan Rebased the branch and DCO check also passed it should merge now 🤞.
@michdolan the DCO is now fine.
@michdolan I think that the PR is now ready. Could you approve and merge this pull request?
