MAINTAINERS: add @kbdharun as org owner

[blueskyson]

Hi, @kbdharun! You've been an active tldr-pages organization member for over 6 months.
Thanks for sticking around this far and helping out!
According to our community roles documentation, you're now eligible for becoming an owner in the organization.

That means you will, from now on, be part of the team responsible for performing role changes (like this one!) in the community.
When performing such role transitions, make sure to follow the process described in the COMMUNITY-ROLES.md document.

Is that OK with you? Let us know!

Either way, thanks so much for all the work you've done so far. You rock!

[kbdharun]

Sure, I would love to contribute and maintain more in future, so I am up for it. Thanks for the issue.

We need an active owner to add us to owners. c.c. @CleanMachine1 @navarroaxel @marchersimon @sbrl

Just a quick note, "members of the tldr-pages organization who remain active for at least 6 months" Hasn't reached that milestone yet.

@kbdharun We can recreate or reopen this a few months later.

If my math's right, you, @kbdharun, have now spent 6 months as a very active organization member. So, would you still like to become an owner?

[kbdharun]

Sure

Done, could you open a PR changing MAINTAINERS.md?
