Add @abayer as an OWNER 🐈

@abayer has contributed features such as step templating
(https://github.com/tektoncd/pipeline/pull/767) and Pipeline level
params (https://github.com/tektoncd/pipeline/pull/471), as well as many
general tweaks and fixes, and 40+ reviews! Not to mention that since he
works on Jenkins X (built on Tekton) he has invaluable feedback from the
perspective of someone actively building on top of Tekton!

Let it be noted forever that @bobcatfish should have gotten around to
doing this ages ago and she very much appreciates @abayer's patience 🙏
