Remove sbwsg from OWNERS_ALIAS file

[ghost]

Changes

I can't remember what OWNERS_ALIAS is used for.

Removing self from approvers lists here just in case
it has bearing on the mechanics of that.

A bit more context: I'm trying to reduce my footprint in open source so that I can focus a bit more on delivering features. I'm still planning to be around to review, lgtm, etc.

Release Notes

NONE

[bobcatfish]

@sbwsg these days OWNERS references OWNERS_ALIAS so if you remove yourself from that list your effectively stepping back from being an OWNER of Tekton Pipelines (and you won't be able to /approve)

(not sure why the productivity aliases are also in this file 🤔 )

[bobcatfish]

(if you're going ahead with it can you add yourself to the # Alumni ❤️ section as well?)

[ghost]

Perfect, cheers for clarifying!

[ghost]

Added self to alumni section.

They are for this repository, for the plumbing/hack part of things
