updating the accessibility advisory council

[tonyfast]

y'all i made an errant commit through the Github interface that should've been a PR 🤦 anyway, i've removed myself from the accessibility advisory council. some can close this right away if they want, it makes the decision easier.

last week, i volunteered to review #142 which was a public communication about accessibility progress. in the revision, i volunteered significant emotional labor bringing up topics like disability advocacy and access. this work was a lot of effort for me and my accessibility expertise was ignored, divisive, and dismissed. i thought my role on the advisory would carry some merit, but it does not. i was actively hurt by the whole experience and reacted by not bringing my best self to communications as the conversation grew. i'm sorry to have overstayed my welcome in this community and to have polluted something i've worked hard to build and support.

i apologize for the harm i might have done. i hope that the jupyter accessibility community can continue supporting each other. i believe in the effort. i hope that disabled can folks enjoy an equitable, assistive interactive computing experience in 2024.
