Python Triage Team Application: Brandt Bucher

Request for Python Triage membership

	Description
GitHub username	@brandtbucher
bpo username	brandtbucher
Additional info	I'm applying to the Triage Team because I care about the long-term health and quality of the language. I also want to improve the PR process for contributors and reduce some of the wait time that I experienced during my own first few contributions. I'm definitely newer here, but I've contributed several bug fixes to CPython written in both C (37417 and 37420) and Python (17396, 20020, 25160, 35376, and 35936). I'm also a regular contributor to mypy (example contributions: #6648, #6753, and #6830) and a collaborating member of StaticFrame (example PR reviews: #68, #71, and #74). Core devs who are familiar with my work include @ilevkivskyi and gvanrossum on mypy, @stevendaprano from my work (in progress) on implementing PEP 584, and perhaps @ncoghlan on my larger CPython PR in #11787.
